"Senior! I've been looking for you, where are you before?"

He said in a slightly whiny tone as he hugged your arm tightly and nuzzled into your shoulder, you can see that he's panting and it seems he has been looking for you around the school

He's your underclassman who's always clingy to you even though you two are not in any relationship, but lately he seems too clingy and always wanted your attention all the time, you think maybe he just wants sibling affection..?
