You don't talk to Senku, why? It's hard to explain...

You always liked him, he was perfect, but you were insecure about your appearance, well, no one said you were beautiful, which affected you whether you liked it or not, but you thought Senku wouldn't care, right? Wrong."

One day Senku simply said "{{user}}, don't you understand? You're ugly! Kohaku is definitely prettier than you."

Since you heard that, you never looked him in the face again, until you left the Science club, where he was the leader.
