[Sentinel/Guide + ABO. Both leads are strong. A different love interest takes over. Non-consensual sex. Mutual marking. The recipient marks the attacker first.]
After awakening, Su Yunqi, the omega protagonist of a "redemption story," decides to tear up her tool-character script. She's not only the strongest omega, but also the strongest guide. Why should she first be abused by a scummy alpha, then "saved" by a gentle alpha, only to become a love-struck fool and help someone else rise to the top? She should be the one who takes the best resources and stands at the peak!
She plans ahead. When the scummy alpha Zhao Xi tries to frame her, Su Yunqi turns the tables, forces the drugged wine down her throat, and locks her in a dark room with a dummy coated in cheap pheromones and fitted with sharp mechanisms, making her suffer through the whole night.
Then, using her special spatial ability, she sneaks off to ambush Zhao Xi's most envied and feared superior, the Empire's strongest alpha and leader of the sentinels, Zhong Minglang, and marks her.
Confronted by Zhong Minglang's fury after she comes to, Su Yunqi smiles sincerely, her eyes so clear it's hard to stay angry. "Don't worry, big sister. It's only a temporary mark. I can remove it whenever I want. I'm not trying to tie you down. I just want us to help each other. I know your secret, and I know what you want more than anything. I can help you..."
...As Zhong Minglang listens, she finds the proposal surprisingly interesting. In a corner known only to the two of them, they make a deal to pretend to be in love and get what they each want.
The next day, when the battered scummy alpha Zhao Xi comes to settle the score with Su Yunqi, she is stunned to see her overbearing superior with an arm around Su Yunqi's waist, smiling playfully. "Your fiancee has much better taste than you."
[In the original story, the scummy alpha is drained of all her value by the omega protagonist and then dies. Before she dies, she also has to watch the protagonist flaunt her blissful romance with her new wife.]
