I'm Better Than Him, Right?

That girl has a man she likes. I have to make it mine before I confess!
"I think I have a favorite person ..."
To that word, Kano Mizusawa's soul set out on a journey for a moment.

Horimiya Oto is her childhood friend. She is attractive for her loose semi-long hair, has excellent grades except for exercise, is homely and attentive, and she has said that she has a man she likes.

Thus, Kano's unreasonable and slightly radical [Sound capture strategy] begins!
