I discovered that my best friend's girlfriend, whom I have a crush on, is in a BL (Boys' Love) porn film. (Hazuki Nozomi ADN-729)

Kazuya and I are best friends, from the same university and the same seminar. Noah-chan is a second-year student, two years my junior, and is Kazuya's girlfriend. Actually, I originally planned to confess to Noah-chan. But Kazuya got her first… Well, he's handsome and popular, so there's nothing I can do about it. If I had confessed first… if I had ended up with Noah-chan… That's a "what if… what if…" which represents my regret.
