@Seth well seyeong has always gave heegae a red light and kept his distance it was heegae who thought seyeong is playing hard to get and seyeong knew it won't be good to grow feelings for each other so he left but a little late because heegae already caught feelings and now thinking that he got betrayed, seyeong never told heegae about being a man in the game, he never said he is a girl either and also returned the money so basically seyeong didn't took his revenge too, heegae is lying to himself thinking that he was wronged and fooled, that guy is living in his own delusions
