I'll Die Another Day (Transmigrated into a Book)

The seemingly grandfather-aged but truly inscrutable male lead X the seemingly Mary Sue but truly cannon-fodder female lead

Wu Tongyu transmigrated into a book, becoming the spitting image of a Mary Sue heroine. To her dismay, she discovered it was a story about a supporting female character, making her the heroine boss that the supporting character had to defeat.

The supporting female character had a System that let her cheat, and kept trying to steal Wu Tongyu's men. Every day, she used every trick in the book to kill her. Unfortunately, Wu Tongyu's wealthy male backer was so powerful that no matter how she tried to die, she just couldn't.

The scheming old fox of a villain gripped her chin and warned her, "If you dare to die, I'll wipe out your whole household and exterminate your entire clan."

Holding the supporting female character's hand, she advised her earnestly, "Why don't you wait a little longer? I'll die another day."

That day, she walked along the end of the long street, carrying a lantern bearing the character for "evening." She bent to smooth her skirt, then looked up at him. In that instant, all the flowers in the capital paled beside the fleeting enchantment in her eyes.

They all said the Right Chancellor had remained unmarried at sixty because he was infirm. He thought that perhaps he had spent a lonely lifetime simply waiting for her to arrive.

One-on-one romance, a faux grandparent-grandchild romance, lighthearted.

[Bonus Scene]

Wu Tongyu clutched the handkerchief in her hand and looked at the old fox before her. She tactfully made her request: "My lord, aren't you going to rebel today?"

"With a lovely wife at home, why would I rebel?" A sharp glint flashed in the old fox's eyes.

Two years later, the useless emperor and the supporting female character knelt at the old fox's boots, begging for mercy. She looked up at the handsome youth who often appeared in her dreams and was so shocked she nearly lost her head.

The beautiful young man put an arm around her slender waist and said, "To avenge my wife, I had no choice but to take this realm."
