Exacting My Loner Revenge on a Perfect Angelic Girl by Sexual Training (uncen-eng) by Shimizuan - Adult Sex Game

It was graduation day. I'd decided to confess my feelings to Sumire Tachibana, the angelic class queen.

"I've always loved you. Please go out with me"
Her response to my honesty?

"Uum...sorry, who are you?"
