throw me in the deep end (слэш)

"Even if he cared to let any of them catch him and spend his heat with him, he wouldn’t choose them for overly respectful bows or fancy gifts. He’d choose someone… someone strong and tall, but gentle and considerate too. Someone kind and smart. Someone whose smile is like a flower blooming; a precious gift to be savored. Someone funny. Someone who likes him. Someone who challenges him, and meets him blow for blow in a match.
Someone like that.
It’s then that he sees Lan Wangji, lifting his head from his bow."

Each heat, a mating run is held to try to find Wei Wuxian a mate. He's never let anyone catch him before. Lan Wangji has never come before.
