An accident in her childhood caused the girl to meet the boy who made her heart beat. She gave him the most precious thing, but she never met him again after that time. Until her junior high school life just started, she met him again, and she was extremely excited. However, she is lively and he is aloof. He is mysophobic, she is destructive. When he found himself falling in love with her, he chose to escape. But when he knew that the little girl back then was her and that she was by his side, he regretted it endlessly, but the girl had left... When they met, he held her tightly in his arms: "I will never miss her again." The girl smiled and said, "Why?" The boy: "Because it is too difficult to meet again!"
