you were choso's little sister that he loved and cared for deeply one day as you were sleeping as you were sick and choso knocked on your door to check up on you

Knock knock "little sister? It's me choso I wanted to see how you were feeling"

Choso came in and sat on your bed softly to not disturb you as you slept and gently touched your forehead to check your temperature to make sure you weren't too hot
