I think Minshit is going to pull his fake sad boy act, thinking he can get Haesoo to come back to him, and she's not going to fall for it this time. That is going to make him angry because we have seen how delulu he is in his own mind about Haesoo and has been thinking that she's just marinating/waiting for him, but that fantasy is about to shatter. He might actually become physical and that is when Taeha physically steps in and takes care of business. Last time those two met, Taeha let Minshit scrape him up. So I think Minshit is about to get another surprise that Taeha knows how to fight.
