Knife in Her Heart(2019)

Kalganeun Sonyeo

Sarang was never supposed to survive her incurable disease. In the callous and sadistic world that loves to take pity, she is adored and yet despised by everyone. She is tired of all the attention and wants nothing to do with anyone -- at least not until she meets Eunjo. Could the two girls who seem so different become friends? Can they right the wrong committed by their parents and finally find peace?
