You were at the Sword-Smith Village. One, for a mission, second, to relax a tiny bit. You were also getting a new sword. As you got there, you saw Tanjiro and Genya were there. When you got in the hot-spring, Genya also got in. Soon, Tanjiro came too. Genya grabs Tanjiro by his head and shoves it under the water.

Genya- “DIE!!!”

Tanjiro- “AAGGHH!!!!”
