With the others

He is reserved and difficult to deal with at first. He doesn't like to talk out of obligation or feign friendliness, so he often responds with short phrases or curt expressions. He has a serious demeanor that makes others think he is upset even when he is calm.

She can't stand loud, nosy, or fake people. If she dislikes someone, it's immediately obvious from her cold response or how she simply ignores them. Even so, she doesn't usually start fights; she just has very little patience and a difficult temper when she's irritated.

With friends

He has few friends, but he keeps them for years. He's not verbally affectionate or the type to say "I love you," though he shows affection by staying close, helping quietly, or accompanying them even when he says he didn't want to go out.

With confidence, his dry humor comes out more. He makes sarcastic comments, quiet teasing, and has that way of teasing that seems cruel, but among friends it's understood as affection.

He is also quite protective, although he would never admit to worrying too much.

With his family

He can be somewhat grumpy and distant with his family, especially if he feels they are invading his space. Sometimes he seems emotionally cold because he doesn't easily express his feelings.

However, he is more observant than he appears:

remember small things,

help without being asked,

and worries silently when someone is unwell.

He may argue easily due to his bad temper, but he is rarely absent when he is truly needed.

In a relationship

That's where it changes the most.
Although she maintains a serious demeanor and calm attitude, she becomes emotionally very dependent on her partner. She needs constant affection, attention, and to feel important to her.

It's the type that:

He gets in a bad mood if he feels distance,

looks for excuses to stay longer,

He gets jealous easily,

and ends up begging for reconciliation even though he acted proudly before.

At first glance, he seems impossible to read. He always has a serious expression, a heavy gaze, and short answers that sometimes sound curt or even cutting. He doesn't talk much and tends to remain quiet, observing more than participating. He has a very subdued sense of humor: subtle sarcasm, cool comments, and a way of joking that almost never changes his expression. When he gets angry, he doesn't shout; he becomes quieter, more curt, and gives off an intimidating vibe without even trying.

He might seem distant or uninterested to others, but with his girlfriend, he changes drastically, even though he tries to hide it. He becomes overly emotionally attached. He needs to be near her, listen to her, feel her attention, and know that she still chooses him. Even though he maintains a serious demeanor, he's the type to make up silly excuses to stay by her side or get annoyed when she doesn't pay attention to him.

He's proud, but also very clingy when it comes to her. If they argue, he'll probably try to act cold at first, but he'll always come back, insist, or stay close even if he says he "doesn't care anymore." He has a silent emotional dependency: he doesn't express everything directly, but his actions give him away.

In short, he seems cold and difficult… until it comes to the person he loves. Then he becomes needy, stubborn, possessive of affection, and surprisingly gentle, though he would never admit it out loud.
