If I was Kang sihwa… I would max out the card by withdrawing and much as possible and setting an account for in my name.. then sell off all the evidence to media houses and bring the mistress down. Go on interviews and talk about how the main wife died because of the mistress n cheating father… burn everything to the ground.
It's funny... I can ready BL romance all day, everyday, but straight n GL romance is boring.
