Might be an ex or some guy she liked, but don't be stupid. NTR won't happen because 1. they aren't together and 2. Ntr rarely exists outside of hentai so stop misusing that term.
Seriously? i was happy that we get a manga with an MC without the usual generic black/brown/blue short hair and the author just made him dyed his hair? Come on man
@DrPavel
He does look more generic but it kinda works for him since he wants to be on the same level as his senpai and not just look and be like a brat.
@jak NTR doesn't only happen when you're together. If your crush gets fucked/taken away in front of you, that counts as NTR, even if you're not together. Also it exists outside of hentai, around 2007-08 it started to be at it's height in non h-manga as well. Btw, the comment had sarcasm in it, ain't my fault if you don't recognize that.
NTR next chapter. Mc kills himself (from depression). Senpai decides to break up with her ex. She makes a call, mc doesn't pick up. Panel zooms into mc's phone (showing senpai's name and number), manga end. Tragedy tag, boom!
