@Creutzfeldt too nice? dude, shes a KID. Kicking her to the streets would be sentencing her to wrong herself again.
What kind of absolute heartless asshole does that? I mean, im not going to help every single person on the street i meet, that would be impossible, but after letting her in, you have taken a responsibility for her, kicking her out knowing her past, and what is going to happen to her on the streets is not only heartless, but borderline criminal.
And kohai really should mind her own damn business. So she´s fine abandoning a kid on the streets because she wants to get it on with her boyfriend? Thats the mark of an asshole, no more, no less. She may be excused to a certain degree because she doesnt know sayu´s past, but that still doesnt make her attitude any less cruel, selfish, and egotistical. The only thing she cares about is if she can fuck MC or not, and doesnt give a damn who she has to stomp in the process to do it.
