My Wingman, Lan Wangji (слэш)

“I want to propose to Lan Huan.”
Lan Wangji spat out his tea, and the liquid flew so far that it completely drenched his papers and somehow ended up spraying Jiang Cheng in the face as well. Jiang Cheng wiped the tea and spit off with a grimace.
“How can you even drink this shit?”
Lan Wangji cradled his mug defensively and shot Jiang Cheng a glare. “It’s soothing.”
“It’s disgusting.”
“You’re disgusting.”
“You-!” Jiang Cheng shook his head. “And why are you so shocked that I want to marry your brother?”
Lan Wangji finally set his mug down. “Isn’t it a bit soon?” Jiang Cheng gaped at him. “There’s no need to rush into these things-”
“We’ve been together for five years!”

(Or five times Lan Wangji tries, and fails, to "help" Jiang Cheng create a romantic gesture for Lan Xichen, and one time he doesn't interfere.)
