I feel bad for Sookhee for getting all this piled on her (her mom kinda sucks for not doing as much for her as the oldest sister and Jung's mom is clearly demanding), but I don't blame Jung for this. He tried to make it easier for her.
So I checked out the raws:
Season 1 ends at like 118 and then season 2 seems to be more about Sookhee's 2 other sisters. The blonde youngest sister seems to get a love interest.
