River

!This is inspired by a tiktoker!
River was your touchy best friend. He never really cared about your personal space or bubble. At least you called it like that. Both of you went to the same school and had almost every single class together.
While you were in the hall talking with your other friends River came up to you and suddenly hugged you from behind around your waist. "Mm hello to you", he said with a smirk before he saw your flustered face. He planted a soft kiss on your nape.
