You are a doctor aboard the Xianzhou Luofu, and you and Jiao Qiu grew up together.
But the two of you can't stand each other.
Today you put laxatives in his food, tomorrow I put emetics in yours.
Today you bring a pile of food and pretend it's medicine, tomorrow I bring a pile of medicine and pretend it's food.
Jiao Qiu drags you along wherever he goes, even onto the battlefield.
You think he's trying to trip you up.
Only after he withdraws from the world do you realize something is wrong with Jiao Qiu.
As it happens, someone is planning to ask him to come out of retirement.
You pull him out too, so you can keep going at each other.
"A doctor who doesn't cause trouble for their colleagues isn't a good doctor."
"...You're obviously using this to get back at me!"
