The comments are not just it lmao. I get their point but in here, it's definitely cheating. They literally just talked about not going to shops like that. Ritsu said that if Rui doesn't want him to do it with other people, he won't. And then what? He still did it despite knowing Rui is NOT OKAY with it. If it's not cheating, then what is it? It's different if they're not together or both agreed on being in an open relationship... but they didn't.
