Mass-Produced Bottoms

A crematorium-style story, perhaps a little angsty? There is a kind of story where a transmigrator plays a cannon-fodder scum gong, mistreats the protagonist, then makes a graceful exit after completing the mission. But the protagonist, having been mistreated, refuses to accept it, turns evil, and destroys the world. The Transmigration Bureau has no choice but to beg the transmigrator to return and save the corrupted protagonist. However... Bringing back a transmigrator who has achieved fame and success out of retirement costs too much. To cut costs and improve efficiency, the Transmigration Bureau has to find another way. And so mass-produced gong stand-ins are born. * "Gentle and obedient" is written into Yu Qi's core code. Every time his boyfriend calls him by the wrong name, he smiles and answers. Yu Qi even comes up with a perfectly reasonable explanation for the name his boyfriend says aloud: "Xiao Yi." The characters in Yu Qi's name can be put together to make Yi, after all. * His boyfriend is young, handsome, and rich. Yu Qi is a model, and although he's only mediocre at his job, he still works hard to support their household. They wish each other good morning and good night, and fall asleep in each other's arms. Yu Qi believes he and his boyfriend are very much in love. So he secretly saves up to buy a pair of engagement rings, hiding them in his pocket so he can propose to his boyfriend. * Not long afterward, Yu Qi's underhanded tactics for climbing the ladder are anonymously exposed. Scandals flood the internet, he loses his job, and everyone around him despises him. Head bowed, he returns home. A light is on in the entryway. His boyfriend is standing by the door, with someone else behind him. Someone who looks about seventy percent like Yu Qi. * Yu Qi is stunned for a moment, then suddenly understands. He is a mass-produced gong stand-in made by the Transmigration Bureau, a copy of the original scum gong. He came to this world to face the corrupted protagonist's revenge, and to embrace and reform him with a boundless, unconditional love. Once the mission is complete, the Transmigration Bureau will send the real scum gong to take his place, hiring him at a low rate to keep the protagonist company for the rest of his life. * The real scum gong is an upgraded version of Yu Qi. Yu Qi looks about seventy percent like him, making him a very suitable counterfeit. According to the Transmigration Bureau's rules, once the real scum gong arrives, the face of Yu Qi in the protagonist's memories will be replaced with the real scum gong's. * Yu Qi smiles as he explains to the protagonist and the real scum gong that he's lost. Yu Qi smiles as he turns and walks downstairs. But when he leaves the apartment complex, he feels utterly lost. The reward for completing a mission from the Transmigration Bureau is freedom. Yu Qi doesn't know where to go, or where he can go. * Yu Qi finds a job waiting tables, and runs into the protagonist. He goes over to offer him a menu. The protagonist turns his head and looks at him in confusion. "Xiao Yi?" Yu Qi smiles and steps aside, revealing the real scum gong, Yu Yi, behind him. Theme: Happiness matters most
