Falling in love twice, with the same person, in exchange for staying together for a lifetime
A milk allergen who is all-powerful but can't cook, and a school bully who can play the piano in No. 1 Middle School. It happens that both of them become people who see the other side, get along day and night, and finally get together. Later they broke up due to graduation and met again at a class reunion. He was so drunk that he hugged her waist and said, "Baby, I was wrong, I miss you so much."
