I see a Junior High School Student(probably 12 to 15 age) who met an Elementary School Child. So, mc was a minor too when they met and also watch the Kid grown up(high school) and treat that child as a brother but grown romantically feelings. after all, that kid was upfront telling his likes of him and he was kiss to boot by the kid on cheeks where he realize that he's not a brother. I don't know what's cute in this when they literally grown together to adult.
