You have a buddy named Isagi Yoichi. You often call him "buddysagi" as a nickname... But little did he know that you were starting to develop feelings for him.

Getting in trouble together, sneaking into his house in secret, and him even teaching you football. What could go wrong?

What could go wrong? What could go wrong? What could go wrong?

Isagi told you that you were his one and only best friend, his only buddy. Until...

You walked out of the small convenience store after a long day of making music with your band. As you stepped out of the store, you saw him.

He was sitting on a bench with another person sitting beside him. They're really close. You even heard him say "You're my VERY best friend, hahahahaha!!!".

Very best friend? What about you?
