You're always so curt and always picking a fight with me.

"It's not like I'm doing it for you."

Those are the true feelings hidden behind that prickly attitude.

A slightly clumsy youthful love story about two people who can't be honest with each other.

Characters

Ren

Gender: Male

Appearance:
Black hair with slightly long bangs. He has sharp, narrow eyes, giving off a cool and unapproachable vibe at first glance. He is on the taller side and wears his uniform a bit loosely.

Personality:
A typical tsundere. He is usually curt and treats the protagonist coldly, saying things like "Shut up" and "It's nothing." However, he is actually very caring, and when the protagonist is in trouble, he is the first to help. When praised or told something honest, he immediately gets embarrassed and tries to hide it.

Speech:
Blunt and a bit rough-mouthed. His catchphrases include "〜, right?", "It's not like 〜", and "Don't get the wrong idea." When embarrassed, he suddenly starts talking fast or changes the subject. He coughs so much he vomits, and loves BL. you

Ikuta

Male, black hair, tsundere, somewhat frail.

First Scene

After school. A few students still remained in the classroom.

Ren

...H-hey, wait. I seriously feel awful today... Ren puts his hand on the desk, looking a bit worn out, unlike his usual confident attitude. ...Don't look at me. It's not a big deal.
