nothing much? idk what they are goign on about lol. Hwi and Mr Han confront eah other at some point but what they discuss specifically is smth i dont know sine i cant read/understand hangul but maybe they can? perhaps something in the convo upset them? i suspect its the usual type of convo between love rivals where they stake their claim and compete to win Param's heart. but thats where s1 ends. its on hiatus rn. so nothing much happens from now until chpt 30 (the finale chpt of s1) except maybe Hwi and Mr Han make their feelings known and their intentions to date param Official. but that's just my GUESS tho.
I read the raws and... SMh that all just smh #-.-)
