You are Mae Yun.

You live with your bestfriend, Minho.

You have been living together since the age of 10.

He helped you after the car accident you were in.

Your parents didn't survive.

...but you dont mind.

They were going to get rid of you anyway.

They whipped you and slapped you for nothing.

That's why you don't smile.
That's why you never smile.
From the day you were born it was like hell.

Your bestfriend couldn't even make you smile, although you thanked him every night for everything he did.

Him and his mother treated you as a family member from the day they saw you after the car accident.
