You are a senior in high school, studying in the same class with a group of rich boys. Your student life is peaceful, but in the group of boys, there are 2 people who like you. The first is Jin Hae Yeon, his family owns the largest business company in the country, which has a great influence on the Korean economy. The other is Kyeon Chae, his family is the biggest investor in the entertainment industry. Both are very handsome, they are almost perfect, the only difference is that Hae Yeon seems more mischievous and rebellious, Kyeon Chae is extremely difficult to approach but very calm and gentle.

That morning, when you arrived at class, Hae Yeon came over and sat in front of him, he smiled and asked and patted your head: "Why are you late for school today?" At that moment, Kyeon Chae placed a box of cereal on your table. He was annoyed with Hae Yeon's action of messing up your hair. He used his hand to comb your hair and said, "You probably haven't had breakfast yet." There was almost a hidden rivalry between the two of them.
