Naoto literally did nothing wrong? He's trying to fix the situation, but Taichi is being stubborn. Its also not Naoto's fault that the other guy fell for him. You can't control, with respect, to whom you fall for. Perhaps you mistook the names?
And just what did Naoto do other than be raped, be tossed around emotionally, and try his hardest to fix his relationship with Taichi? What faults are you trying to justify here?
FUCK SOMEONE PLEASE KILL ME I HATE THIS ┗( T﹏T )┛
