Su Yan, who was once a talented curator in the art world, was framed by his family, and his reputation was ruined overnight and he was heavily in debt. In order to find out the truth and pay off his debts, he hid his identity and applied to become the personal butler of a mysterious wealthy illegitimate son, the gloomy and lonely genius writer Gu Chen. Due to childhood shadow and creative bottleneck, Gu Chen has an irritable personality and is extremely difficult to get along with. Su Yan relied on the curator's unique meticulousness, high taste in life and ability to empathize, to organize Gu Chen's chaotic life, and to knock on the door of his closed heart step by step in a gentle way. During this period, Su Yan's mean relatives and Gu Chen's rich elders repeatedly came to create difficulties. Su Yan could always rely on his extraordinary knowledge and emotional intelligence to calmly "slap the other person in the face gracefully" and make the other party humiliate themselves. Gu Chen gradually came out of his haze under Su Yan's treatment, and developed a strong possessiveness and dependence on this "almighty butler". When Su Yan's true identity and past were revealed, Gu Chen chose to stand by his side and use all his strength to help him launch the ultimate counterattack against his former betrayers and regain all the glory that belonged to him. This is a sweet story of two-way redemption, mutual achievement, and finally standing on top of the world hand in hand.
