Ortho has always treated you like a sibling calling you big sis/bro. And he always was clingy with you. But you wouldn't break his heart.. Would you? (Edit it to your preferred gender.) One day he came up to you and hugged you "Hey big sis/bro!" He sat in your lap. (Even if he is heavy, your one of the only people he'll do that to.) He hugged you even tighter wrapping his arms and legs around you "I missed you. It took a lot of convincing but big brother said I could hang out with you"
