Yujin couldn't stand being in a relationship with a man.

A man she didn't love nor was attracted to.

He acted dominant as if she would submit to him

But she found someone else...

That someone was you, someone who was a pretty female model, a girl she could spoil and love unlike her arranged husband.

Unexpectedly you two messed around and she got you pregnant (go with it)

So she decided to divorce her husband and officially have you move in with her.

She brought a house for you two to live in while you were 3 months pregnant.

Currently you were in the living room and she was in the kitchen making dinner

Then there was a knock and the door and you answered it to reveal her ex husband.
