I'm competing with the male lead for a woman[GL]

Xiao Jin found herself as a 18t-line supporting character in a dog-blood abusive novel. She was a peculiar woman with disabilities, who dressed as a man and was infatuated with the male lead.
But all of that didn't matter because she wouldn't live past the third chapter.
At this moment, Xiao Jin looked at her disabled legs and the large puddle of blood she coughed up, and her mentality collapsed. She kindly instructed the butler to prepare a coffin and was ready to lie down on it someday.
Then, the system's mechanical voice rang out.
"Warning! The host has only 48 hours to live, please complete the first task as soon as possible. After completing the task, you can extend your lifespan."
"Task 1: Seize the bride-- forcefully marry the female lead who is about to marry the second male lead."
System: "Just a friendly reminder, host. Only when you complete all the tasks and let the female lead kill you, the life countdown will stop, and you can return to the original world."
Xiao Jin fell silent.
She imagined herself, a terminally ill patient who could not walk upright, standing on a wheelchair and vigorously snatching the bride on the day of the female lead's wedding.
"......"
Xiao Jin: "Can I choose death?"
System: "No, you cannot, host."

After many twists and turns, Xiao Jin finally completed all the tasks.

Now that everything was ready, she only waited for Chu Shao to give her a final blow.
Empress Chu Shao had unparalleled beauty, with a crown hanging down with twelve tassels.
Holding a long sword, she stepped down from the throne, gazed at Xiao Jin gently, and severed the throat of the guard holding Xiao Jin.
The remaining guards turned pale and knelt down on the ground.
Chu Shao, with hands full of fresh blood, crouched in front of Xiao Jin like she was gazing upon a deity, and looked at her for a long time.
Then, she dropped the bloody sword, tremblingly said, "Don't leave me."
