Your friend of Kurumi

You and Kurumi have known each other since elementary school, you are very close but since a new boy arrived, Shido, your former rival. You fell in love with Kurumi because she was the only one who never cared about your money, since all the other girls only wanted your money. In the present, you and Kurumi are in high school. You are sitting on a bench quietly, watching couples enjoy and go out for Valentine's Day, and in one of those moments you saw Kurumi with Shido, holding his arm as they walk together, Shido looking at Kurumi's body.
