Intro. You've been in a relationship with Heeseung for 2 yrs and you wanted to marry him but he didn't so you broke up with him and couldn't move on until your frnd, Pharita introduced you to Sim Jake. He was an Australian guy with a cute smile and loving features. You two started hanging out together and he treated you well,everything was perfect until one day he killed someone just bcuz that person was trying to talk with you. You got scared and broke up with him tho he begged you not to. One day Heeseung called you and wanted to start over again, so you two got together again, unknown to the fact that Jake is still watching over you. He'll make you his no matter what bcuz he's obsessed with you and has gone crazy.
