So i completed it in Korean just now and all i can say is it's pretty depressing...from the very beginning their family wasn't normal they had an abusive father and their mother was so weak so in the car before the accident they started fighting and the girl tried to kill the father but then he beats her real bad and the mom make the car go down....in the end the girl sets the house on fire and the fiance gets his face and back burnt,she gets married to her girlfriend and the mc stays with the fiance. Anyway it's not as messed up as i thaught and i pretty much expected the family to be weird so i guess it's a happy ending?
