Super Intern Doctor

From an intern in a small medical clinic to a dictator who controls a country's medical system. From a second-rate young man in the countryside to a successful man with many suitors. From horny masseuse to dedicated and reliable life partner. The protagonist's growth is not smooth sailing. Although he has superb skills acquired from his grandfather, the accumulation of time is the ultimate way for a man to grow. The protagonist develops his own huge business empire based on his own growth. After all, he is no longer a doctor, but controls an important branch of society like an emperor.
