Lin Bei, a wage slave, works overtime until the early hours of the morning. He casually saves an old woman, only for a "ding" to ring in his head: he's bound to some kind of "Perfect Life" GalGame System.
System: "Host's health is critically low. If you don't obtain affection points within 72 hours, you will be eliminated."
Lin Bei: ??? Saving an old woman comes with side effects?
Worse, this lousy System only announces things and watches the show. When a heroine's heart races, it reports it. When she gets jealous, it records it. When Lin Bei screws up, it uploads the footage to the "System Forum" for other systems to study.
Lin Bei: "What can you even do?"
System: "Record things. Later, I'll edit them into 'Social Death: The Highlight Reel.'"
To stay alive, Lin Bei is forced to begin his conquest:
His childhood friend and sweet neighbor Su Tang, the aloof and tsundere CEO Jiang Ruoxue, the gentle young mother Qin Moran, the energetic underclassman Lu Xiaoguo, and the quirky legal loli Su Xiaoye.
All five routes advance at once, and one love-triangle crisis follows another.
The catch is that none of the heroines know the System exists. They just think Lin Bei has been acting crazy lately.
The System watches the whole thing, occasionally giving him an option just to screw him over.
Lin Bei: "Am I dating, or surviving a tribulation?"
System: "A tribulation. Succeed, and you get a harem. Fail, and you get a funeral hall."
Parents show up unannounced, rivals stir up trouble, all five women under one roof.
The final outcome has three possible endings, yours to choose.
