Rin

Hair
Dark black, straight, and slightly messy. It falls in strands over her forehead, giving her that "I don't care about anything" air that she clearly does care about.
2. Eyes
Intense turquoise green. They're the most striking feature of her face. A cold, penetrating gaze, as if she were analyzing you… and probably judging you a little.
3. Face
Fine and quite attractive features. An expression almost always serious or indifferent, with that touch of superiority that he makes no effort to hide.
4. Complexion
Athletic and slim. He's not overly muscular, but well-defined, typical of a fast and technical striker.
Height
Tall, but tall enough to command attention without looking gigantic.
Presence
It's not just his looks. He has this intimidating vibe that makes him stand out even without speaking. Like he's always in "competition mode."

Not at all cloying
Forget about messages like "good morning, princess." If he texts you, it's because he actually has something to say... or because he remembered you exist between workouts.
He shows affection, but it's strange.
He's not one for sweet words. His version of affection would be something like:
“Don’t get distracted.”
"Take care of yourself."
Translation: Yes, he cares about you, he's just emotionally frozen.
Priority: football
You're important... but not more important than his goal of being the best. If he has to choose between seeing you or training, you know who wins. Spoiler alert: it's not you.
Protector in his own way
He's not sweet, but if someone hurts you, he won't let it go. He won't say it nicely, but he'll take action.
Silent jealousy
He's not one to make a scene. But he does become colder or more curt if something bothers him. You have to guess, because communicating emotions isn't his strong suit.

Cold and calculating
Rin thinks as if everything were a game of chess. He doesn't act impulsively, but analyzes each move to crush his opponent in the most efficient way possible.
Obsessive about perfection
Winning isn't enough for him. He has to completely dominate. If something goes wrong, he gets extremely frustrated because his standards are ridiculously high.
Competitive to the point of obsession
His life basically revolves around being the best. He doesn't play for fun, he plays to prove his superiority. And if he loses… well, he doesn't exactly handle it with emotional maturity.
Distant and inexpressive
He's not affectionate or sociable. He has trouble showing emotions and often seems indifferent or even arrogant. Not because he "wants to be bad," but because he's too focused on his goal.
Motivated by personal conflict
Much of his personality stems from his complicated relationship with his brother, which makes him more intense, resentful, and determined.
