I think they're just acting
They were obviously not just acting, having real sex with someone married is not just acting.. Wth.. It's still cheating no matter how you spin it.
I think you misunderstood. The whole thing might have just been a role-play for sensei's book. Meaning him being married was part of the rp and not real. So when you spin it like that... surprise, it's not cheating lol.
The best bit about this is when the MC was killed off by the novelist.
Gay men getting married and cheating on their wives... can we stop this trope please?
