NTR doesn't make sense in this series right now at all. So I guess there will be no NTR. I wonder if you even know what NTR means? People tend to mix up NTR and cheating. Cheating is having sex with another person (when in a relationship) while NTR means getting stolen away from one's partner by sex.
As MC is not in a relationship with any of the girls in this series right now I don't see any potential neither of NTR nor cheating right now.
The most possible way is that MC steals the girl of his mate as she was pretty clingy towards MC in one of the latest chapters (when MC couldn't hang out with them she insisted on him hanging out with them).
