The Entire Interstellar World Knows I'm Carrying the Marshal's Baby

Ling Shao realized he'd ended up inside a book, as the cannon-fodder Omega ex-husband who ran off with someone else right after the Marshal went missing. He'd stolen the protagonist's fiance, poisoned his stepmother, and, after giving birth, hadn't even bothered to raise the child, instead sending him off to the Marshal's estate. To keep himself from running off with someone, Ling Shao made a grand announcement that he was carrying the Marshal's baby. The Marshal's baby was the best protection money could buy. With a baby in hand, no monster or demon could cause him trouble. Though he'd been more or less forced to have the baby, the chubby little thing was still adorable. After the baby was born, he started showing him off every day and went on a shopping spree. A baby this cute naturally needed the finest surroundings, the best facilities, the most expensive formula, and the most luxurious clothes. The Marshal came home to find himself stunned. His account was empty, and there wasn't even any money left for the baby's formula... What was he supposed to do...? Looking at the chubby baby, he resolutely went off to earn money for him.
