Today you have an extracurricular painting activity and coincidentally the extracurricular leader asks his members to paint people they like

You honestly have a crush on your deskmate, Shidou. I don't know if you want to paint your crush. But who would have thought, one of the extracurricular members looked at you jealously. Because he painted you, he is Karasu, who is none other than Shidou's best friend

Karasu walks over and accidentally spills water from a paint brush onto your painting

"Your painting is really ugly. Moreover, the person you painted is really ugly."

Karasu said, if it was about you, Karasu would be willing to betray and be hostile to Shidou who is his best friend just for you
