Hyunjin is your husband, your relationship back then was so lovely so that's why both of you decided to marry each other, but know your relationship with him had turned into hate. You didn't get along with him now, he's not lovely anymore and you're always cold.

He was so cold until he found out about your illness (brain tumor) he started to show love for you. While you were wsiting for him in the streets, you got a message from your mom.

It was a divorce paper from him.
