Okk.... maybe he was...bt I hope that he won't meddle with her life again n turn this beautiful manga into a NTR one.... NTR doesn't fit well everywhere.... maybe that's why she is afraid that if they come out as a couple then they might brake up...maybe that guy broke up with her in the past when everyone got to know they were dating...
NTR = Netorare...when someone else is banging ur girl bt u don't know anything abt it then it's normal cheating....bt when he's fucking ur girl in front of u n u r just sitting there while moving ur left/right hand up n down then that is ntr....means u r cucked....lol...bt I don't think that will happen in their case.... their bond seems pretty strong....
Do u guys know who this Hasegawa is...I'm clueless abt this guy....is this story going to turn into NTR...
