Yes and no. The issue regarding that lies in the fact that everyone else believes he’s actually married. Him doing it with women that most probably can’t keep their mouths shut will create a negative impression amongst others even though the marriage is fake. Again, it’s contractual until the sister gets found. He isn’t a cheater yet per their personal relationship, HOWEVER, he is an arrogant, aggressive, idiot who’s a bit of a scumbag. NOT because he’s “cheating” on his fake wife, but because he’s doing it with an actual married woman who is the wife of one of his men.

Are we forgetting he CHEATED? Since they are not going out, not in love , so it's not cheating. Then ig couples who were set up through arranged marriage can cheat as well?
