The Protagonist's Comeback System

What do you think of the supporting characters who turned the tables on you? Protagonist of an apocalyptic rebirth story: As they say, if someone can steal your partner, then that partner wasn't worth keeping. If I've lost one tree, I've still got a whole forest. Protagonist of a transmigration palace-intrigue story: Wah, wah, thank you so much! I've had my eye on my fair-skinned, beautiful, gentle, sweet cousin for ages. That male lead? Whoever wants him can have him. Protagonist of a dark, obsessive story: I want to give the supporting character who turned the tables on me 120,000 likes!!! Damn it, reading about twisted, dark people in a novel is one thing, but having to deal with one in real life is a matter of life and death!!! Protagonist of a reborn revenge story: Honestly, losing a partner who was supposedly devoted and utterly loyal is pretty sad. But getting another chance and seeing everyone still alive is what matters most. Protagonist of an xianxia cultivation story: …Sure, I can't die no matter what, but that supporting character is still a real pain. What's the point of keeping an eye on me all the time? With such narrow horizons, ascending to immortality is just a dream.
