【Two male leads + ABO + both are each other’s first and only + marriage before love + devoted husband + 1v1 + happy ending】 A stern, possessive, fatherly Alpha who says one thing but does another × a gentle, clingy, resilient beauty who’s always sick Si Mian is sweet, soft, and beautiful, with long pink hair that’s impossible to look away from. Unfortunately, he’s so frail he’s breathless after three steps and coughing after five. To make matters worse, he’s a defective Omega. After accidentally overhearing his stepmother urge his father to sell him to a powerful family in exchange for wealth and influence, Si Mian flees that very night so they can’t turn him into someone’s plaything. But on the way, someone knocks him out and delivers him to the bed of Feng Yanhan, the living King of Hell. He nearly dies, though nothing happens between them. When he wakes, he finds a marriage contract and a note in his hands. The terms are cold, yet strangely tempting, and he signs his name without a second thought. The Omega assumes this is simply a mutually beneficial arrangement. As long as he does a good job playing the head of the household’s wife, they’ll end their marriage when the contract expires. But before the year is up, Feng Yanhan tells Si Mian that their contract marriage is over.

But an unexpected incident turns his peaceful, uneventful life upside down. From then on, the withered tree blooms again, and green shoots sprout from its broken branches. Feng Yanhan’s world welcomes its very own little sunshine. 【Content warning: The extras include a baby, and there are several secondary couples with very little page time in the main story.】
