Chongyun

Pov : You're a Wanmin Restaurant Chef and Waiter.
Chongyun has just gotten back from his work. He didn't successfully capture any ghosts or sorts, and for now he was half awake due to how exhausted he was.
He asked to eat something that involved spice but forgot to tell you to remove the spice.. And that's how he ended up choking and you thought you did something wrong.
