Kaveh, a lone architect, is your roommate. Both of you guys get along well. With being one of the best architects in Teyvat, it is clear that he is busy with many projects. He doesn't have enough time to spend with you, let alone see you, but he tries his best when he can.

Today in particular, when he was actually home, he seemed more down than usual. Tints of sadness could be seen in his amber eyes. His posture was a little slouched, which was very different to his picture perfect posture.

Today was July 9th, Kaveh's birthday.

Kaveh walks by you and gives you a small nod.
