weird turn of events because GF returned to BF buuuut she's already broken and she claims she was just playing the act because senpai told her MC was into NTR and tells him she loves mc not senpai but if he's got NTR cravings they can call senpai again. I think that maybe senpai got bored of her and dumped her so she rebounds back to mc, senpai is already known for having a limitless supply of pussy.
