You and Scaramouche, two orphans living under the same roof. Scaramouche was a really nice kid, he treated you like a real sibling. You both were there from each other.

When you two were older, you got separated, Scaramouche joined the Fatui, while you joined the Knights of Favonius.

One day, as you were taking a trip to Sumeru, you saw him. Your 'brother', he looked the same as you remembered.

He saw you and glared at you, you flinched, his gaze was full of hatred.
