Chen Xi'an was bound to a System and sent to a mission world. The System ordered him to follow the plot and complete his task.
After arriving in this world, Chen Xi'an fell deeply in love with it. Here, his body was healthy, society was more advanced and accepting, and there were endless possibilities for him.
He wasn't thrilled about having to do missions and win over the protagonist, Shen Mo, but he gritted his teeth and put up with it so he could stay.
Just as the mission was nearly complete, the System suddenly told him, "Your mission is almost done. The points you've accumulated can send you back to your original body."
What? It was going to send him back? Chen Xi'an refused.
He started slacking off, dragging his feet, and finding all sorts of ways to sabotage things.
What they didn't know was that the protagonist they were trying to win over could hear their conversations.
And Shen Mo had never fallen for Chen Xi'an at all. He'd only pretended to, hoping to gain benefits from the System.
When he heard that Chen Xi'an would leave once the mission was complete, Shen Mo was the happiest person there.
But as Chen Xi'an's performance on the mission got worse and worse, Shen Mo began to panic.
He dropped to one knee and proposed to Chen Xi'an on the spot, then took him to register their marriage the very next day.
As long as they were together, the story would have a perfect ending, and Chen Xi'an would have to leave.
To stay, Chen Xi'an had no choice but to find another way out. He pretended in front of the System that he'd fallen in love with Shen Mo, and that he'd do anything to stay with him.
System: "Are you sure you want to stay here? If you return to your original body, the points you've accumulated will cure your illness, too."
Chen Xi'an: "Waaah, I don't want to leave Shen Mo. I can't live without him."
System: "There's someone in your world who's been waiting for you, your high school deskmate, the person you had a crush on. He's been secretly in love with you, too. Ever since your accident, he's deeply regretted not confessing. If you wake up, you can be together."
Chen Xi'an: "Can Shen Mo come back with me? I want to be with him."
System: "Sorry, Host. That's not allowed."
Chen Xi'an: "Then I want to stay here."
In the end, the System respected Chen Xi'an's wishes and left him in the mission world.
It also gave him one piece of advice: "The fairy tale has ended. No one can control what happens next. Take care of yourself." Then it left.
As soon as the System was gone, Chen Xi'an's expression changed. He turned to Shen Mo and said, "Come on. Let's go to the civil affairs office and get a divorce."
Shen Mo: "What are you talking about, darling?"
Chen Xi'an: "Stop pretending. I know you can hear me talking to the System. Now that it's gone, there's no need for us to keep up the act."
For the first time, Shen Mo truly saw Chen Xi'an for who he was.
For some reason, he didn't want a divorce anymore, even though he'd once looked forward to being free.
Shen Mo: "We can get divorced, but first explain what's going on with that deskmate you had a crush on. You promised me before that I was the only person you'd ever loved."
