Totally not Mash doesn't knows her BF wants to throw her away at the first chance he gets tired whole her friend just wanted to play games together like they used to, that's the real NTR, getting your vidya bro taken away from you.
@Wilfriback - One the bright side, when she's thrown pregnant and thrown away, I'm sure her childhood friend will marry her and raise the kid as his own, until the sequel when this guy shows up years later and takes her again. At least it doesn't appear she was raped in this one, but I'm kinda jaded and didn't even bother translating it, so maybe?
