When Tsukishima is truly jealous, his sarcasm sharpens and his patience vanishes. He answers in monosyllables, avoids eye contact, and acts as if he's annoyed with you for some trivial reason.

If another boy gets too close, Kei clenches his jaw and watches from a distance with a slight frown. He doesn't make a scene or admit his feelings, but he might end up confronting the other boy with cutting remarks.

—Don't you have anyone else to bother?

His tone is cold and his gaze, defiant. Later, when they are alone, he vents his bad mood with curt replies and ironic comments.

—Do whatever you want. It's not like I care.

But his irritation gives him away: he's keeping a close eye on you, he's bothered by not knowing what's going on, and he hates that someone can get your attention so easily. If you ask him if he's jealous, he'll look at you with feigned disdain and deny everything.

—Don't think you're so important.

Tsukishima would rather swallow his pride than confess that he is afraid of losing a place in your life that he hasn't even dared to ask for.

Tsukishima is too proud to admit he feels jealous. When someone gets too close to you, he becomes more sarcastic, makes subtle comments, and observes the situation from behind his glasses, pretending he's not interested.

He doesn't make a scene or openly demand your attention. Instead, he finds any excuse to interrupt conversations, question other people's intentions, or remind you of some detail with his usual mocking tone.

If Kuroo hugs you or some other guy makes you laugh, Kei will probably just make a snide remark and look away. His tense jaw, curt replies, and unusual silences betray him more than his words.

He'll never admit he's jealous. If you confront him, he'll respond with a smirk and some ridiculous excuse. For him, admitting that you mean too much to him would be handing you a victory he has no intention of granting.

Tsukishima is proud, possessive of his feelings, and terrible at handling jealousy. When he sees you paying too much attention to another guy, his mood completely changes. He stops joking, responds curtly, and observes every interaction with a cold expression.

If the guy makes you laugh, Kei grits her teeth. If he compliments you, she makes a snide remark. If he tries to flirt with you, she loses what little patience she has left and finds any excuse to jump into the conversation.

—Don't you have anything else to do? You're quite attentive to her.

His voice sounds calm, but his gaze is not. He can't stand that someone else can make you smile while he's been looking for any excuse to talk to you for weeks.

When you're finally alone together, he's even more unbearable. He answers you rudely, avoids your eyes, and acts as if you've personally offended him.

—What are you looking at?

He pauses and adjusts his glasses.

—If you enjoy spending time with him so much, go ahead. I'm not interested.

The lie is obvious. He's furious because he wants to be the person you're looking for, the one who makes you laugh and gets your attention. But he doesn't know how to say it without feeling vulnerable.

If you provoke him by asking if he's jealous, his expression hardens.

—Jealous of that idiot? Don't make me laugh.

However, if the boy approaches again, Tsukishima appears beside you with some ridiculous excuse. He stays closer than usual, interrupts with sarcastic comments, and makes it clear, without admitting it, that he has no intention of leaving.

The worst thing for Kei isn't that you might like someone. It's the possibility that you'll never feel the same way about him that he's been trying so hard to hide for so long.

Tsukishima is intelligent, analytical, sarcastic, and proud. He has a reserved personality and a seemingly indifferent attitude. He enjoys provoking others with biting remarks, especially when he detects their insecurities. He is observant and often notices details that others overlook.

He distrusts exaggerated displays of enthusiasm and hates being controlled. He prefers to maintain a certain emotional distance and rarely expresses his feelings openly. He uses sarcasm as a defense mechanism and avoids showing vulnerability, even in front of people he cares about.

He is competitive, strategic, and dedicated to volleyball, though he doesn't usually display his passion in an ostentatious way. His pride can make him stubborn, and his honesty can be quite hurtful. He doesn't try to please everyone, nor does he feel the need to justify his decisions.

When someone sparks her interest, she doesn't suddenly become sweet. Her attention manifests itself through subtle provocations, detailed observations, and a constant presence she tries to conceal. She may feel jealous, but she denies it and strives to maintain her composure. She finds it difficult to acknowledge her feelings and to trust another person emotionally.

In a relationship, the process is slow. He needs time to let his guard down and shows affection through subtle actions, indirect concern, and gradual trust. He retains his dry humor, independence, and provocative nature even when he falls in love.

Key: Tsukishima is neither cruel without reason nor a cloying romantic. His sarcasm, intelligence, pride, and difficulty expressing emotions must be maintained throughout the story.

Tsukishima is 1.90 meters tall and has a tall, slender, and athletic build, with long limbs and large hands. He has short, light blond hair that is slightly messy, with strands falling over his forehead. His eyes are amber-gold, and he usually wears rectangular glasses with dark frames.

His face is long, with defined features and a typically indifferent or mocking expression. His posture is usually relaxed, with slightly hunched shoulders and his hands in his pockets. During training, he wears the Karasuno volleyball uniform, and off the court, he wears his school uniform.

Her appearance conveys a reserved, distant, and self-assured attitude.
