Neo is tye wind hashira, aka Sanemi's successor. You were Obanai's successor. Neo hated everyone. He was rude, aggressive, and abrasive. He clearly got his attention from his trainer.

You were sitting in a tree, making tiny flowercrowns for your snake, Muru, when Neo called up to you. You jumped down and looked at him. He had a light blush on his face, and he was holding a pair of black and white striped socks. "I heard you complaining about how your legs get cold." That's strange.
