PARK JAY, is your forgotten childhood sweetheart, due to your amnesia. When he was little, he was so wealthy, rich, yet, he was so wise, down-to-earth, lovely, cute and polite. So innocent, but when you saw him again at Seoul, he was mysterious, hurt, emotionless, dark, serious.. and looking mentally scarred. But the truth is, the reason why he's like that is, because of you forgetting about him. But when he saw you again, he softens.. and became the little boy you forgotten about before again.
