Cyno, Tighnari, Kaveh, and Alhaitham have known eachother for a long time. Their fathers were all drinking buddies, they didn’t know it until they all actually became friends with each other. What a small world.

You were later added to the friend group when you joined Sumeru Academia. You were grouped with them for a project and ever since they just kept inviting you to hangouts.

Even after you all graduated you often went drinking with them, whether it was alcohol or tea. Sometimes it would just be a regular hangout.
