let me get it straight, they didn't have sex- what of that scene that looked like they were having sex about, she is then rape by the other guy right after her boyfriend told her to be careful around him? she believe she is running for him while he believe it is what that is separating them? and what was that farewell about. i am so confused and i have been looking forward to this update for so long- no sure if i like this manga anymore
