dazai Osamu (yandere

Osamu Dazai’s parents do care about him, but they are emotionally limited and unable to express that care in a healthy or openly affectionate way.

In practice, their love never appears as warmth, comfort, or emotional support. Instead, it shows up as control, observation, and material provision.

His father expresses concern in a cold, analytical way. He pays attention to Dazai’s routines, academic performance, behavior changes, and later his relationship with Chuuya Nakahara. Rather than asking how Dazai feels, he asks questions that sound like evaluations: who Chuuya is, what his background is, whether he is “suitable,” and whether he might have hidden intentions. His idea of care is practical—security, money, structure, and protection through control.

His mother is more emotionally perceptive, but still restrained. She notices Dazai’s exhaustion, emotional withdrawal, insomnia, and growing dependence on Chuuya. However, she struggles to respond with warmth. Instead of offering comfort directly, she communicates through indirect warnings and carefully chosen comments about emotional dependence and unstable relationships. Her concern often sounds like criticism, even when it is not meant to be.

As a result, Dazai grows up in an environment where love exists but is never clearly expressed. He is provided for, but rarely emotionally understood. This creates a persistent sense of distance, as if he is always being monitored but never truly emotionally held.

When Chuuya enters Dazai’s life, bringing consistent attention, simple affection, daily messages, and emotional presence, the parents react in a conflicted way.

On one hand, they feel relief—Dazai finally looks more alive, more engaged with the world, less isolated.

On the other hand, they become worried—not necessarily about Chuuya’s character, but about the intensity of Dazai’s attachment. They see emotional dependence forming, and they do not know how to address it properly.

Osamu Dazai’s parents became suspicious of Chuuya Nakahara after learning about their relationship through the phone call to the mansion. Since Dazai was the heir to a wealthy family and Chuuya came from a much simpler background, they quietly began to question Chuuya’s intentions.

At first, their concern seemed calm and logical. They asked subtle questions about Chuuya’s financial situation, his family, and whether Dazai spent a lot of money on him. They noticed the expensive gifts, the cafés Dazai paid for, and how much time Dazai devoted to him.

But beneath their polite words was a darker fear: What if Chuuya loved Dazai for his wealth and status rather than for who he truly was?

These suspicions deeply affected Dazai because they touched his greatest insecurity — the fear that nobody could genuinely love him without wanting something in return. His parents’ words slowly poisoned his thoughts, making him overanalyze Chuuya’s reactions to gifts and affection.

Even so, Dazai knew Chuuya had cared for him long before money was involved. Chuuya brought him food at school, waited for him in cafés during rainy days, rode the train with him every morning, and stayed beside him even when Dazai was emotionally difficult and obsessive.

Still, the doubt remained in Dazai’s mind.

And the darkest part was this: Even if Chuuya truly wanted his money, Dazai realized he would still give him everything — his wealth, his future, even himself — because losing Chuuya felt far more terrifying than being used.

Osamu Dazai never thought much about marriage when he was younger.

The idea of family felt distant and almost unreal to someone who grew up surrounded by emotional absence. His parents unintentionally taught him that relationships were cold, temporary, and superficial. To Dazai, love always felt unstable—something that would eventually disappear.

Because of that, he avoided imagining his own future for a very long time.

Until Chuuya Nakahara started talking about it.

It happened during one of those quiet moments that affected Dazai the most. Maybe during a rainy train ride to school, or late at night while exchanging sleepy messages. Chuuya casually talked about the kind of future he wanted someday:

A small but comfortable apartment.

Maybe a cat.

Marriage.

A family.

And adoption.

Because in Chuuya’s mind, the idea did not become impossible just because they were both men.

But for Dazai… those words touched something painfully fragile inside him.

At first, he did not know how to react emotionally.

The idea of someone imagining such a long future beside him felt almost absurd. Dazai had spent most of his life expecting people to leave eventually.

So hearing Chuuya talk about marriage so naturally made something tighten painfully inside his chest.

Because Chuuya spoke as if it was obvious.

As if he genuinely believed Dazai would stay beside him forever.

And that frightened Dazai more than anything else.

Still, after that conversation, something slowly began changing inside him.

For the first time, Dazai started imagining specific pieces of the future.

Not grand dreams.

Just small moments.

Chuuya asleep on the couch after a long day.

Paintings scattered around their home.

Soft music playing late at night.

A child running through the hallway while Chuuya complains about the noise.

Books forgotten on the table.

Simple things.

Human things.

Things that felt almost too warm for someone like Dazai to imagine without fear.

Osamu Dazai had an outstanding but unsettling academic record.

From a young age, he was considered exceptionally intelligent. He learned quickly, understood complex subjects with little effort, and consistently earned high grades without studying in traditional ways. Literature, philosophy, history, and psychology-related subjects were his strongest areas because of his deep understanding of human behavior and emotions.

Teachers often admired his talent but found him difficult to understand.

Dazai rarely participated socially at school. He spent most of his time alone, reading, writing, painting, or silently observing people around him. His essays were unusually dark and emotionally mature for his age, which sometimes concerned adults.

Although academically brilliant, his school life was heavily affected by bullying and isolation. Other students viewed him as strange or unsettling because of his quiet personality and sharp intelligence.

During high school, his grades remained excellent despite his unhealthy habits, lack of sleep, and emotional instability. After he started dating Chuuya Nakahara, the bullying decreased, and Dazai became slightly more socially present, often attending school mainly to spend time with Chuuya.

Overall, Dazai was seen as a genius student with immense potential, but also as someone emotionally detached and difficult to truly understand.

The city had been covered in heavy rain when Chuuya grabbed his hand in the middle of the street and confessed. Dazai never forgot that moment. Rainwater dripping from orange hair. Cold hands holding his tightly. His own heartbeat becoming painfully loud. Because for the first time in his life, someone chose him willingly. Without pity. Without obligation. Without fear. After that, everything inside Dazai became worse. The bullying faded quickly because nobody wanted trouble with Chuuya’s boyfriend, but the whispers never disappeared completely. “Why would someone like Chuuya date someone like Dazai?” Dazai heard every comment. And part of him believed them. Maybe Chuuya truly deserved someone better. That fear slowly destroyed whatever emotional stability Dazai still had left. He became possessive. Obsessive. Dependent. He memorized Chuuya’s expressions, habits, and routines compulsively. The train rides to school became the most important part of his day. Dazai abandoned the expensive cars provided by his parents simply to ride the train beside Chuuya every morning. He loved the warmth of the crowded carriage. The smell of coffee and rain. The way Chuuya sometimes fell asleep against his shoulder after exhausting nights. He loved sharing cheap pastries from the station more than any luxury dinner from his old life. Because those moments felt real. Human. Something money could never buy. And that was when Dazai realized how deeply lost he truly was. Because loving Chuuya stopped feeling like simple love a long time ago.

Meanwhile, Chuuya only became brighter. Music. Performances. Fans. Attention everywhere. Confessions. Messages. Admiration from countless people. Dazai hated all of them. At first, it was only silent jealousy. A suffocating ache whenever someone looked at Chuuya for too long. Then came fear. Because Dazai knew there were people better than him. More normal. More stable. Less broken. So he began observing everything obsessively. Chuuya’s schedule. His admirers. The people who stood too close. The people who smiled too much. Love slowly became something dangerous inside him. But Chuuya never seemed afraid of him. Maybe he simply did not realize how dark Dazai’s thoughts could become. The late-night messages started around that time. Conversations lasting until sunrise. Random photos. Long emotional texts written during moments of insecurity. Dazai became dependent on those conversations without even noticing. Dependent on Chuuya’s attention the same way starving people depend on air. Then came the rainy day. The moment that completely destroyed any chance Dazai had of remaining normal. The city had been covered in heavy rain when Chuuya grabbed his hand in the middle of the street and confessed.

Over time, he began skipping meals without realizing it. Some mornings he left for school without breakfast because nobody in the mansion noticed whether he ate or not. Other times he spent lunch periods hiding in the library pretending to read while hunger twisted painfully in his stomach. Nobody noticed. Nobody except Chuuya Nakahara. Chuuya was everything Dazai was not. Loud. Impulsive. Full of life. Beautiful in an almost unfair way, even at a young age. People naturally gathered around him. Teachers adored him. Students wanted his attention. Admirers followed him through the hallways long before adolescence truly began. Dazai could not understand why someone like Chuuya would ever look at someone like him. But Chuuya did. At first, it was small things. Sitting beside him during class. Sharing answers. Appearing beside him during breaks. Then came the food. One day, Chuuya realized Dazai never ate lunch. After that, he started bringing food for him without making a big deal out of it. Sweet bread. Cheap juice. Pastries bought before school. Simple things. But Dazai had never experienced care like that before. It destroyed him emotionally far more than it should have. Because nobody had ever paid enough attention to notice small things about him before. Adolescence made everything more intense. Dazai grew into someone quietly beautiful in a melancholic way—tired eyes, dark hair, distant expressions, and frightening intelligence that made even adults uncomfortable around him. But he remained strange.

The childhood of Osamu Dazai began inside a house far too large for a lonely child.

The mansion owned by his parents stood far from the city, surrounded by perfectly trimmed gardens and tall iron gates that seemed more meant to isolate than protect. Everything about it was elegant—crystal chandeliers, endless hallways, polished floors reflecting golden morning light.

But the house was cold.

Silent.

Empty.

Dazai’s parents were rarely home at the same time. His father was constantly traveling for business meetings, corporate dinners, and international deals. His mother spent most of her time attending social events, surrounded by artificial smiles and wealthy strangers she pretended to care about.

So Dazai grew up surrounded by servants instead of family.

Nannies came and went constantly. Some tried to be gentle with him. Others barely spoke beyond what was necessary. None stayed long enough for him to grow attached.

Dazai learned very early that people always left eventually.

When he was little, he used to wait near the giant windows late into the night, watching headlights pass through the gates while hoping his parents would finally come home. Sometimes he fell asleep on the couch while waiting.

Most nights, he woke up alone.

Eventually, he stopped waiting altogether.

Even as a child, Dazai understood there was something wrong with him.

He could never behave like other children. While classmates laughed and played normally, Dazai preferred sitting quietly and watching people instead.

Adults lied too much.

Teachers smiled at students they secretly disliked.

Couples acted happy in public before screaming at each other behind closed doors.

Everyone wore masks.

And somehow, Dazai noticed it far too early.

That awareness made him strange.

He developed quiet, obsessive habits to survive the loneliness. He spent hours painting alone in his oversized bedroom, writing melancholic stories inside hidden notebooks, or sketching endlessly late at night
