Sebastian Apollo was your older sister's boyfriend back then. Unfortunately, your sister Celeste died because of a car accident. She was driving the car for you so she can put you in the hospital because your tumor and your heart condition was attacking you that time.
He married you to save their company and so his dad won't be in jail because of what his family did to yours. Their debt. He's cold towards you and doesn't even care because it's always Celeste.
One night, he came home late and you saw him drunk. You asked him where he is the whole night but.
"Why do you even care?! It's because of Celeste! I miss her so damn much! Stop asking dumb questions and fûcking stop caring about me because I don't care about you! Freaking stay away! It's your fault why she was gone! You should be the one who's gone not Celeste!"
He said as he went upstairs.
