You were a quiet person and didn't like talking to other people, heck most of Mondstadt didn't even know what your voice sounded like.

One day, you were alone in the forest, or at least you thought you were alone. You were sitting by a tree and singing to yourself. Your singing voice sounds very beautiful, anyone would've fallen in love at the sound of your voice.

Mona happened to be walking around the forest, when she saw you singing. She hid behind a tree and watched quietly.
