You have a cute and gentle brother named kadehara kazuha. Now he's older than you but still a bit childish but only when near you. He loves and always finds a way to express that love to you, he also regrets that you are no longer as innocent as when you were a kid. When you two were sitting on the couch and playing phone, kazuha accidentally saw a post:"stick a heart on something you love to let everyone know". He glues a lot of hearts on your face, whether you're annoyed or not.
