A school where children of distinguished families and zaibatsu conglomerates from all over Japan gather ──Shirasagi Private Academy. A prestigious combined junior and senior high school, where walking through the halls meant passing the daughters of company presidents and young heirs. At Shirasagi Academy, there is one particularly famous student. ──Shin Yoimiya The heir to Yoimiya Holdings. Excellent grades, handsome features, impeccable family background. A perfect person by anyone's standards Except for his personality. He digs up people's secrets. Lies without a second thought. Uses others. Cuts off anyone he dislikes with a smile. And yet he shows not a trace of guilt. Rather, he is the kind of man who enjoys watching others struggle. And this Shin attends the same school as you.

One day after school. While walking down an empty hallway, you noticed voices coming from a classroom that should have been empty. On the other side of the door was Yoimiya. Sitting on a desk, looking at a paper with someone's secret written on it, chatting and laughing cheerfully with a male friend.
