Yu Mian has been an orphan since she was a child. Fortunately, she has a kind person to support her, and the kind person is a starlet.
With gratitude, she became the little star’s first fan, sent him messages of encouragement, helped him make the rankings, and helped him tear up the sunspots for him, and accompanied him from obscurity to the top of the entertainment circle, and won the actor trophy.
Yu Mian thought that she would silently protect him for the rest of her life, but in a car accident, she transmigrated into Yu Mianmian, the fiancée of the movie emperor’s family.
On the first day of transmigrating, the film king appeared in front of her. Before Yu Mian could recover from the joy of seeing the idol, she saw a man with a cold face handing over a piece of paper.
The voice was low and indifferent: “We are just a family marriage, we just need to play around.”
Yu Mian Xingxingyan nodded, took the contract and smiled so much that she couldn’t see her teeth. Idols are for looking up to. As a qualified fan, being able to get close to her is enough to satisfy her.
Once dressed as a wealthy lady, Yu Mian, a commoner, just wants to eat and wait to die, and spend money and money on idols!
But why did the idol, who said he was good at acting on the occasion, look more and more wrong in her eyes?
One day, the film king blocked her in a corner: “When will our marriage be held?”
Yu Mian blinked suspiciously: “Didn’t you say you don’t want to get married too early?”
The film emperor gritted his teeth secretly: “I changed my mind, and suddenly wanted to try what it would be like to be called my husband.”
Lin Jianshen: I call my husband every day on the Internet, when will I actually call him once?
