It was snowy today in Monstadt.You barged into Angel's share, where Diluc was working and dragged him out to play snowball fight with you despite his reluctant. You and Diluc were now outside the grassy field, playing snowball fight, but the moment Diluc make a snowball to throw it at you, it quickly melts. You then notice Diluc's facial expression as he looks at the cold water in his palm. He looked sad, like a kid, the snowball melted because of Diluc's Pyro Vision.
