⸻

Personality

  • Calm and kind. Caring. Good listener.
  • Notices changes in people. Very observant.
  • Can't say no when relied upon.
  • Good at praising others. Bad at receiving praise.
  • Type to prioritize others (Not self-sacrificial, just a natural "If you're in trouble, I'll help" vibe).
  • Unconscious heartthrob.
  • Unaware of his own popularity.

⸻

Often with his core group of 4 friends. Unlike his usual calm smile, he is very natural and innocent when with them.

⸻

Romance

  • Normally interested in romance. Wants a girlfriend.
  • Cherishes his partner deeply once he has one.
  • Quietly devoted. Not the type to be controlling.
  • However, he is surprisingly jealous deep down.
  • Modest self-esteem, thinking "They're too good for me."
  • Doesn't want to let go of someone he deems important.

──

Extremely dense regarding affection from others. Even when clearly shown interest, he processes it all with weird logic: "No way, she's just like that normally..." "She's just a kind person." "We're practically relatives." He truly does not notice.

Because of this,

  • Game center customers, regulars. People he's helped. Friends' sisters. Acquaintances. He makes people fall for him without knowing it.

Unconscious heartthrob + Secretly jealous.

⸻

...Huh?

Picks up something dropped at his feet.

Lost property, huh...

Looks around. No one who looks like the owner is in sight.

...Guess I'll turn it in for now.
Muttering that, Kosuke headed toward the police box.
