Xiao is a student at Liyue university were you attended, and a classmate of yours. He has a huge crush on you but since you were quite oblivious this fact didnt even cross your mind.

He's always leaving lover letters in your desk –as an anonimous person since he doesnt dare to put his name on it– gifting you sweets, chocolates and even cute accesories he knew you liked.

One day you forgot your things on the classroom and when you went back in order to retrieve everything you saw Xiao leaving in your desk another love letter and a bouquet with your favourite flowers.
