(No pregnancy or childbirth in this story, just a fake pregnancy. Both leads are each other's first and only partner, as is customary in this genre. Handsome top, beautiful bottom.)
A spoiled mad dog x a beautiful, sickly man who knows how to bend without breaking
At the Spring Banquet, the emperor got drunk and, on a whim, arranged a marriage for the second son of General Xie, who had stayed behind in the capital. His chosen match was a sickly man.
When Xie Linyuan woke up, he stormed home in a rage and found the residence decorated with tall red lanterns.
Lan Shu sat by the bed in white, moon-pale robes. Slender and pale as snow, he gazed at the handsome man with tear-filled eyes. "Second Master, give me one night. Please save me."
After that night, Lan Shu got his wish and stayed in the residence.
At first, Xie Linyuan felt awkward around him. But later, when he saw Lan Shu's belly growing bigger by the day, he realized Lan Shu was pregnant.
Xie Linyuan was all flustered as he took care of Lan Shu.
Later, through countless nights, Xie Linyuan held his wife in his arms, immensely grateful that he hadn't refused the marriage.
That was until the Xie army breached the imperial city and the truth came out. His wife escaped amid the chaos with the military tally, leaving behind a note.
"How can a man get pregnant? Xie Linyuan, are you an idiot?"
Only then did Xie Linyuan realize his wife was a spy, a fraud.
Hatred surged through him, and he swore he'd make Lan Shu pay.
Bonus Scene
Six months later, Xie Linyuan went south to Jiangnan to help his father resolve a salt-licensing case. He heard that a wealthy merchant in the west of the city was colluding with bandits to sell salt licenses.
All the way there, Xie Linyuan listened with interest to stories of the merchant's romantic escapades, then boarded the boat.
But there he saw the merchant in a red fox-fur cloak, painting by a window against a forest of brilliant red maple leaves. When he turned to look, his small, snow-white face was as cold as a handful of snow on a winter's night.
It was the wife who had run away.
Xie Linyuan smiled and closed the door behind him.
"Weren't you pregnant?"
With Lan Shu looking terrified, Xie Linyuan gave a sharp tug and undid his belt, scooped Lan Shu up around the waist, and tossed him onto the bed.
"If you can't get pregnant, you won't be leaving this room again."
.
Lan Shu was being tormented on the bed until he couldn't take it anymore. He took Xie Linyuan's hand and pressed it against his now noticeably swollen belly, crying and gasping, "Husband, feel it. Lanlan is pregnant."
