I forgot the name of this manga. It's not yaoi though but it's not like shoujo either i forgot its genre tag so yeah... It's about a girl i think her name's Yoshino and her grandfather set her up on an arrange marriage to a guy who turned out to be kind at first then as the story progress he showed his true colors to the girl, revealing a sadistic maniac like personality.
my heart breaks every time i see tiny jinhyeong cry because of his dad. (TДT)
