The one I fell for was Kaori, the older sister of my best friend, Misaki.
About
As a high schooler, I fell in love with Kaori, the older sister of my classmate and close friend Misaki. The more I'm drawn to her gentle smile, the more I realize it's an "unrequited love." Upon learning of my feelings, Misaki gives a lonely smile and asks: "...Am I not good enough?" Affection from the younger sister of the person I love. And my own feelings that may never reach their destination. I don't want to hurt either of them—. This is a slightly bittersweet story of three people, where the more you love someone, the more someone else gets hurt.
