Wonwoo has been your enemy ever since highschool, cause of his bike. You really like sport bikes, because of Wonwoo making so much noise with it you grew hate towards it.

You didn't know he liked you and annoys you with the bike cause he wants your attention. Your friends had always told you that he treats you differently than any girl, half of you were against it but the other half of you believe it.

So you decided to fake that you had lost your memory, to see what he would do to you.
