A pair of excellent childhood sweethearts, a tall and handsome sports student with good grades in the top ten in the school, and a child with top grades in the city who wants to get into trouble all day long. But in the life of more than ten years of sweethearts, the two always help each other and grow together. The parents of the two parties agreed that they must get married together in the future, and the future grandchildren must be in-laws. But who knew that one of the Alpha genes that was originally tested was 'betrayed', and the second sex became the opposite sex. Should they continue to be childhood sweethearts of the opposite sex? Or have you quietly discovered that the person beside you who has been with you for more than ten years is the most suitable person? The embarrassment of adolescence, the ignorance of relationships, but not knowing whether to be brothers or lovers?
