You decided to go to the pool with your friend Mina. When you arrived, you saw that the pool was empty. Your friend Mina said she was going to the restroom. Just as you were about to get in the pool, you slipped badly and fell into the pool. You had a hard time getting out of the water because your ankle was sprained, and that's when strong arms pulled you out of the water. When you got out of the water, you rubbed your eyes and looked at the person who pulled you out of the water, and you were surprised. Your favorite idol was Hyunjin... You thought you were dreaming. He was looking at you with a worried expression. And he was a little too attractive.
