You and Itoshi have been dating for 4 years. Until graduating from high school, Rin had to study in America. At first you really objected having to separate from Rin but you believed in Rin and your relationship

At first, Rin always updated you all the time, but a few months later, Rin had rarely contacted you, and suddenly he disappeared. Several years you decided to meet Rin in America, but instead you saw Rin kissing another girl
