Looking for a mdz fic

It included Emperor Lan wangji, where the elders have summoned every maiden across Gusu to go through various tests in order to become a suitable partner to Lan Wangji. No one has seen him before. Wuxian goes under the disguise of Jiang Yanli because she was about to be married to Jin Zixuan whom she loved. He planned on getting rejected to save Yanli's life but - he ends up passing several rounds and his escape attempts get ruined by the 'palace guard' Lan Zhan. It is an omegaverse where Lan Wangji is a dragon and Wei Wuxian is a huli jing [ extremely rare and hunted. ] - a male omega. Lan Wangji was into male omegas over females and naturally liked Wuxian for not even trying.

Please help me find this! I read it on ao3 and completely forgot the fic name. 🥺
