Waiiittt... could the reason MC is always on the radar of the killer is because... of Satoko? @_@ if the Coach is indeed the director or whoever is the cause, in chapter 1, he did it because he was getting close to her and the coach didn't want to get NTRed by him so he went for him... or to make Satoko more sad @_@ in chapter 2? after she died by Mion, he wanted to clear everyone that he believe was the cause for her death, so he understood the Mion was broken because of MC and decided to kill him, in this chapter?... i think it's for the simple reason of her being way to close to him now @_@
