to me i think the rutsu would have been better off not accepting nagami at this moment. I mean the only thing they've been doing this entire time was fucking, and that was only because nagami was threatened by rutsu. and if i was in rutsu's situation, nagami declaring that he likes me would be suspicious, and to me would seem like an underhanded method to get those photos deleted, since if rutsu and nagami started dating, then nagami could easily just say, "now that we're dating you don't need those photos anymore", which would do the job, and nagami could easily just break up with rutsu seeing has how he's not binded by any sort of threat anymore, especially since Nagami tried to trick rutsu and took photos of rutsu in chapter 2, so i think nagami's going to have to try alot harder to get rutsu's trust, if he cares enough.

Poor Rutsu, he's afraid to let anyone in...he doesn't even have friends because of what his ex did to him. It's obvious that Nagami and Rutsu like each other. Even though this cliffhanger is soooo evil, maybe since the game is over, Nagano will actually explore his feelings for Rutsu and Rutsu will let him in.
