I like everything in the series. The animation, actors, and actresses. But I really hated the ending. I was not expecting it. It was so unbelievable because we all know that Woong was so into Yumi, but why did Woong suddenly act like that at the ending. And their breakup does not have a clear reason. I really don't clearly see the reason for their breakup. It was perfect but the ending wrecked it. I cried when they broke up 'cause I really rooted for them.
