Wrong wrong wrong. Opinion doesn't matter here because he did in fact cheat on him. If you understand Reichi's personality, he seriously thinks that kissing someone else or having sex with someone else doesn't count as cheating as long as he only loves one person. If you REALLY read the prequel and this sequel properly, you will understand that simple thing.
I don't really feel like shiratori cheated... I think he really only did have dinner and talk about something important.... He probably cudnt explain properly Bcuz of his terrible lack of communication....
