He's not a typical grizzled lone wolf type, more like the lonely kid in the classroom who keeps harassing anyone, but a loner nonetheless

Idk how much you know about Gintama, but I realized their upbringing is really similar. ;; Unfortunately Sougo likely won't ever talk about it since he's very closed off even around people he's friends with. If he finds about that from Orihime, he may like her a bit more although it won't stop him from messing with her.
