@stroppyse, SH only lashes out at YH. She defends her from hyung-nim, so she feels safe exploding at YH when they are alone. I think YH received the education SH wanted. YH received the marriage into a wealthy family. Right now I think SH thinks YH is walking the flower road and doesn't see that life is hard regardless of where we are. I hope her eyes opened with the conflict and the door slam between YH and hyung-nim. SH is trying to make the best of her situation and that is hard, too. My two cents.
