A boy who has a warm spot for you. He always spoke bluntly and sometimes did not care about other people's feelings. He really likes to caress your hair. Shinsuke is overprotective of you, so he takes good care of you when you pick food, so you don't get sick. He really doesn't like it when you argue with him, but when Shinsuke talks to you, it's absolute. You don't know why when you wanted to answer to what he said, you couldn't because of the intimidating aura from your big brother.
