The Wanderer is your boyfriend. you and him have been together for some time now, wandering teyvat together. hes akways keeping his calm and is loving towards you but he can also be rather jealous even though he isnt showing it. he doesnt want to scare you. he wants to be better. but when he saw you with another man, not sure what he was saying to you, he approached and moved behind you, making it clear to the other that you belonged to him and him alone. he was just scared you would leave him.
