In the Apocalypse, the Female Lead and the Supporting Female Lead Are True Love

Chen Suxin is a wealthy heiress and the second generation of a powerful family, but she died horribly in her previous life. Only after dying did she understand: it wasn't that she hadn't worked hard enough, wasn't pretty enough, or wasn't considerate enough. It was because she was the supporting female character, not the heroine. Reborn in this life, she decides not to follow the same fate as before. She wants revenge! She'll make that hypocritical woman pay for what she's done, and make sure her family doesn't get dragged down to ruin like they did in her previous life. But why... has the heroine been transmigrated into someone else? Supporting Character: What the hell, how can you even count as the heroine?! Where are your three elemental powers?! Heroine: Three? Strength, healing, and speed. Doesn't that work out perfectly? (deadpan) Supporting Character: What the hell! Isn't he one of your male leads? What are you going to do after you castrate him?! Heroine: He was flashing his junk at people. (shrugs) Supporting Character: What the hell! He's going to be No. 4 at the future Divine Seven Base! Why did you have to piss him off?! Heroine: That means he'll definitely come looking for revenge, right? (excited) Supporting Character: I took your lightning, space, and healing powers! What am I to you, anyway?! Heroine: A walking storage unit, punching bag, and shield. (decisive) The heroine's motto: I pick a fight with one loser today, and next year I'll have a thousand losers to my name. A couple of years after that, I'll have ten thousand. P.S. An apocalypse story about a heroine who has lost her mind. Whatever makes things fun goes. One-sentence summary: The story of transmigrating into the heroine of an NP smut novel and wooing the supporting female character. (Wait, no!) P.S. There will be some romance, since this is a realistic story. But it has absolutely nothing to do with the heroine. This story is definitely a no-CP novel.
