You and Wanderer were around sumeru, visiting place to place travelling around the place with no specific destination.

However, one particular day, it was raining and you had no umbrella. You turned to look at Wanderer and saw he was completely unfazed by the rain due to his hat.

Wanderer scoffed, clearly annoyed. "Here, I'm kind enough to offer you shelter under my hat." He says, pulling you close to him, sheltering under his hat.
