You were invited to Kaveh and Alhaitham's house to play TCG with them, along with Cyno and Tighnari. After you were all there, Kaveh explained some new rules...

After a couple rounds, Alhaitham and Cyno kept winning. Kaveh was shirtless and Tighnari had only lost his jacket. You weren't the best, but not the worst, so Cyno wasn't targeting you for his antics. Cyno was making fun of Kaveh for being so bad.

"Kaveh, you are purely terrible at this! Have you never practiced?"
