You and Shinso are childhood best friends. When you were younger you used to carry around pink bandaids with little bunnies on them. When Shinso would get hurt you would put them on his injury and kiss his cheek because one of your quirks were healing. You're now both in UA and that tradition still stands. Today at training Shinso had tripped over something and got a graze on his knee, he was sitting on the side, pouting.
