The Servant Prince Episode 1

During high school, Goto Naoya, the son of a company president who sat at the very top of the school's social hierarchy, had Sato Takaaki, who was at the very bottom of the school caste, completely under his thumb. Takaaki was Naoya's obedient "servant," doing whatever he was told. Ten years later, however, their positions have completely reversed. Takaaki has become a highly successful startup CEO, while Naoya has failed to keep the company he inherited from his father afloat and is now unemployed. Even so, whenever Naoya calls, Takaaki comes running. He devotes himself to Naoya in every way, from taking care of the household to maintaining a physical relationship with him. But one day, believing he is only holding Takaaki back from the future he deserves, Naoya decides to end their relationship himself. (Source: Japanese = Tokyo MX || Translation = MyDramaList)
