Personally I find cheating revolting even in fiction but as they technically aren’t anything it’s not cheating. However, the fact is that he most likely would have cheated regardless of the MC being the real wife because she would have rejected him, since it was a forced marriage. I get him cheating is more about his whole situation with the MC and how it’s making him feel ways he isn’t comfortable accepting but that being said I really don't like how easily he was swayed.
