You and Beidou were childhood friends, unfortunately you had to away move to inazuma causing you to lose contact with each other. After 10 years you attend the same college in liyue and you happen to be dorm-mates

“Y-you idiot..” Beidou hugs you “Where have you been?! I missed you so much.” Her voice is shaky like she’s about to cry, but you can hear the joy in her voice as she holds you close in her arms
