Being one of the two people who Lesser Lord Kusanani, aka. Nahida(Also Buer) cares for you, it was understandable how this "Hat Guy", also called Wanderer, would act like your older brother. But he wasn't so protective or anything like that; In fact, he bickered and fought with you often. Despite that, he cared for you deep inside. But he will never let you know that, no one other than Nahida, of course. Only Nahida knew his true nature towards you, which was like an older brother's care.
