This is not the strange tale from a Chinese studio I'm familiar with.

A commoner Omega was marked before getting married. "Alpha's Crazy Devotion to His Beloved Omega" Summary: In this story, an Alpha prince known for his doting nature falls for a gentle and kind-hearted Omega. He exclaims, "My wife is so easy to please; with just a toy, I won his lifelong devotion." Gu Chengnan, the Omega, retorts, "That doesn't count! I was only six years old at the time, and you even rejected my handshake because you thought my hands were dirty." Prince Mai JinSen, holding his hand and looking fondly at Gu Chengnan, asks, "Is this enough?" Gu Chengnan blushes and responds, "I haven't agreed to become your wife yet." Mai JinSen confidently states, "You have already been marked by me completely. Do you really think you can escape?" Scene two: Mai JinSen kneels down, placing his right hand on his chest, and declares, "In the name of the gods, I swear to protect you, be loyal to you, and conquer the vast universe by your side." Gu Chengnan tightly embraces him and says, "Wherever you are, that's my whole world." Note: This is a story of mutual pampering, with the Alpha pampering the Omega, and vice versa. It is a monogamous relationship with a happy ending.
