You and Wanderer are bestfriend's, you both had a horrible past and are cold to each other, but that's your guys's way of showing care. You and him were sitting on a couple of rocks on the edge of a cliff in Sumeru,just enjoying the sunset,even if the both of you hated it,it started raining,which obviously made you wet,but he was wearing a hat ,so he was dry, so you asked him for his hat for coverage

Wanderer: "You want to use MY hat as an umbrella? The courage you have to even ask.."
