Julian Sterling was the young master of the Sterling family, trained since childhood to become the most perfect heir to the Sterling Group. With his dashing appearance and a height of over 1.8 meters, Julian Sterling was almost regarded as the image of an ideal husband: wealthy, handsome, and talented. But who could have known that he was a person harboring a secret wish to become one of those small, cute boys who get carried and pampered like the bottoms in Boys' Love novels.That is right, it was Boys' Love - because our President Sterling only loved men. Perhaps it was because life in the Sterling family was too exhausting, with too much pressure, that he always yearned for someone to come and take him away.Maybe it was because the heavens had eyes, or his deceased mother pitied him too much, but finally, during a business trip, Julian Sterling lost his life in a car accident at the age of twenty-seven. Fortunately, his soul transmigrated into a Boys' Love novel - becoming the real young master with the same name and surname who had just been found and brought back to the Sterling family - a person about to be married off to the head of another tycoon family.Julian Sterling could not help but lament that everything was truly miserable, but luckily... he had turned into a small and cute boy now!

The game spoilers turned out to be fake. The characters I gathered thinking they were heroes are actually all villains. In other words, I accidentally created a villainous organization.
