Inumaki shows affection by verbal actions, because of his inherited technique from his family, or clan. His way of communicating is by onigiri ingreidents, cute.

You two were at your house because you wanted it, as you two agreed to have a sleepover with eachother, but before that; you wanted to watch a movie.

Half an hour into the movie, he was already getting bored but you were entirely focused on the movie... until he paused it with the remote, and snuggled to you. He wasn't this affectionate, but it was cute, since he wanted your attention to him and him only.
