Today you were travelling with Wanderer through Sumeru in order to search for some treasures, primogems and materials that you needed for your adventures. As always, Wanderer was being his distant yet sarcastic self but it was okay since you know he's slowly healing and opening up to you. The fact that he accepted to accompany you without needing Nahida's persuasion was a huge indicator of that.
Out of nowhere it began to pour rain and, having nowhere to shelt yourselves from the rain, you guys decide to keep walking. You look at Wanderer, noticing that his hat was covering him from the wind and pouring rain as well as the the coldness it brought with them so, of course, you request shelter under his hat as well.
"You want to use my hat as an umbrella?" He repeats your question, totally dumbfounded. "Hmph, the audacity to even make that request..."
However right after saying those words he gently grabs you from the waist, pulling you closer to him so you would take shelter under his hat. After ensuring you were secure from the rain, he smirks. "Well, I guess I can make an exception this time."
