Quick Transmigration: After the Backup Love Awakens, He Sacrifices the Official Partner to the Heave

[Two male leads, 1v1, both are virgins, dominant male, sweet and pampering, submissive male, no female lead]
Jiang Zui, a strategist in the quick transmigration game, accepted a "difficult" mission at his superior's repeated request—to save the simp.
As a result, wherever he went, he could see a stupid sycophant wagging his tail and begging for the protagonist's affection.
But who is he?
How could someone who once held the reins of a leading man do something so shameful?
snort!
Do you want him to be your lapdog?
Maybe in the next life.
The protagonist (the bottom) takes the initiative to turn around, and the protagonist (the top) kneels down and begs for mercy.
He's stopped being a simp, now he's got a successful career on one hand and a wife on the other—a true winner in life.
