To Minwoo, the girl of his dreams was like a leaf to him and he described himself as the root – the root that will always support her and protect her in many ways. Unfortunately, the girl didn’t feel the same way as him and instead, she used him to get herself close to his group of friends in order to make herself well-known. On the other hand, a girl named Hyeri was always watching Minwoo from far and yet, she couldn’t bring herself to confess her love to him because of one reason – he couldn’t forget that girl even when he knew she used him.
