Tian Lei is the "Black Sheep" of the legendary Tian Group. A man who rules the family's darkest business interests with an iron fist and a cruel heart. His temper is a wildfire, and his penthouse is a revolving door of servants who flee in tears. He doesn't believe in loyalty. He only believes in power. When Ziyu applies for the position of personal butler, Tian Lei expects him to break within an hour. Instead, he finds a man who is chillingly perfect. No matter the insult, the impossible task, or the danger of the underworld business they navigate, Ziyu remains unshakeable behind his silver half-rimmed glasses and flawless suits. Frustrated by Ziyu's robotic composure, Tian Lei makes it his personal mission to tear down his butler's walls. But as he digs deeper into the life of the man who serves him, he begins to realize that Ziyu's perfect service is a mask for something much darker. In a world where everyone is an enemy, the most dangerous person in the room isn't the one holding the gun, it's the one pouring the tea.

Due to a drastic record of failed marriages, an anonymous inventor decided to release an app that was installed in a wristwatch. The app's name was Hóngxiàn which means 'red thread'. It wasn't just a normal invention. This app can actually detect your soulmate. People doubted it at first. But when public records showed divorce rates suddenly crashing, the whole world started paying attention. The Hóngxiàn Watch became a massive deal.

The Hóngxiàn Watch holds a dark, complicated secret, and it seems destiny has a serious, unexpected surprise in store for its newest customer.
