[Two male leads + quick transmigration + multiple-slice + genuinely vicious] 1v1
Lin An is a once-in-a-century genius in the Male Protagonist Department. But the quick-transmigration department has too much work, poor conditions, and too many Hosts running away, so his team leader forcibly transfers him to the Cannon-Fodder Department, claiming that the capable should do more.
Lin An has no choice but to accept reality. After working through several worlds, the Cannon-Fodder Department discovers that he's a "genius": every time, he gets the protagonist so deeply in love with him that the plot falls apart.
He's told to play the vicious idealized lover of a powerful man from the capital's elite circle. He takes several million from the man and runs away, and the man breaks his leg trying to find him.
He's told to play the ill-tempered young master of a general's household. He constantly provokes and bullies a wretched slave, who ends up seizing the throne and giving it to him.
He's told to play a selfish local tyrant in a story set in a bygone era. He's lazy and greedy, and beats or berates the protagonist, who actually sells his blood to pay for his medical treatment.
