[Reducing Mosaic]SSNI-548 I liked her first, but all I could do was watch as my unrequited classmate had sex right in front of me… Yura Kanano

[Please also see the PR! ] A situation in which someone else preempts the unrequited love partner who has not conveyed his feelings to BSS (I liked him first) and has not been in a romantic relationship. It is similar to NTR, but since no romantic relationship has been established, no one is at fault, and you can enjoy strong self-loathing and depression. This work is a drama about a man who can't do anything because he has a romantic relationship with her best friend before he can tell his favorite girl, who is the royal road situation of BSS.
