I'm gonna be honest. This kind of character who rejects the mc and shows up a few years later as a "potential" love interest is sickening. If in the next 10 chapters she be either clingy or b*tchy, I can guarantee this to be a trashy series.
as someone who already coldly reject him and make him traumatized girl doesn't have any right to rejoin the race, hope she just gonna be wingwoman and ends up with mc friend instead
