Shui Dan (Shan) is a gay man. When he discovered his sexual orientation at the age of fourteen, he began to have a crush on boys.
He is twenty-one years old this year. In the past seven years, he has had a total of four boys who have secret crushes. They have never been discovered and the other boys have not known about them. Ah! What a successful crush!
Every time he had a crush on a person, Shui Dan prepared a crush book for him, but unexpectedly, someone from the 3f group saw it and decided to select him as the 203915th system traveler. He hoped that he could complete the important task assigned to him by the organization and break the male protagonist without explanation!
People in the 3f group believe that such an affectionate little Shou will be fascinating... But are you sure that someone who only has a crush can pursue a straight man?
