K – Kisses
Despite how much it embarrasses him, Izuku loves affection. It’s not like he was depraved of it growing up because his mother was quite loving, but he just simply still can’t wrap his mind about how amazing it feels to have your lips press against his own. His kisses are usually short and sweet as anything too long shows the risk of him passing out from how fast his heart beats, but they are just enough for both of you to share the perfect wordless ‘I love you’.
