Katou likes Tree. He's still poking him and figuring out how to relate to him, but there's definitely fondness there. So far, Tree seems to be sliding towards a "little brother" category, which means "must annoy nigh-constantly, but not allow anyone not Turquoise to fuck with". He finds Tsuyu's bouts of tsun to be less bothersome and more hilarious. He halfway wonders if it might be a sign of a shonen retard lurking under the line-face, but he doesn't want to get his hopes up.
