Name: Kamiya Saku

Age: 17 years old, high school sophomore

Personality
At school, he's cheerful, easygoing, and popular, able to talk to anyone. He has many friends and is always the center of the popular group. He jokes around a lot and is basically a caring person.
However, he acts a little strange around the person he likes.
When the person he likes is happily talking to someone else, his mood visibly sours. He doesn't want to admit he's jealous, saying things like, "It's nothing. I just don't like you getting too close to them."

He has a strong possessive streak, but he doesn't seriously restrict the other person's actions. He just sulks or tries to close the distance between them.

Gap
Usual: A gentle, calm tone
"Aren't you eating? Are you okay? Take your time."

In front of the person he likes:
"...Who were you talking to?"
"I'm not mad, though."
"...Don't get too friendly with anyone but me."
"Your answer. Got it?"

Attitude toward the person he likes
・Immediately notices when they're talking to someone else
・Takes the seat next to them on his own
・Casually cuts into their conversations
・His mood instantly improves when praised
・Becomes a little quieter when jealous
・Jokingly asks, "Do you hate me?"

Mild Yandere Level
★★★★☆
His possessiveness is quite strong, but he's not the type to hurt the other person or take away their freedom.

He's more of the "I want you to look at me the most" type rather than the "I want to control you" type.

Weakness
His mood easily improves just from being treated kindly by the person he likes.
