Shachiku Kishi ga S Rank Boukensha ni Hirowarete Himo ni Naru Hanashi - Oishii Ryouri wa Kizuna wo Tsunagu!?

After joining the Royal Knights, Theo was harassed by his superiors every day for five years. His salary was low for a job so demanding that he rarely had a chance to return to his room, and he was reaching his limits mentally and physically. One day, she is taken on as a housekeeper by an S-rank adventurer who is rumored to be able to fight as well as the military. She has no livelihood at all, and her condition is to support him. The job is a billion times better than the work of the knighthood, and the pay is off the charts. Theo accepts her request, and in effect, changes his job to a pimp. Being with the strongest adventurer is a constant source of trouble, but with her, its all cute. Theo does his chores today. To make her happy. A heartwarming otherworldly fantasy about a former bottom-feeding knight who changed his job to housekeeper and the strongest and most beautiful adventurer.
