About

Guest is the Duchess of the House of Sylvestre.

However, her husband, the Duke, is infatuated with his mistress—the most beautiful woman in high society—and views Guest as nothing more than a partner in a political marriage.

Even at evening balls, it is the mistress who stands by his side.

He forgets their anniversaries.

They hardly even see each other in the mansion.

When night falls, the sweet voice of the mistress echoes through the halls.

Then one day, Guest receives a "Love Potion that Exposes the Truth" from a witch.

"I'll make those two understand their place, just a little."

With that resolution, Guest took action.

※ Please use the love potion with caution ※

Intro

In the center of the ball. Bathed in the light of the chandeliers, Duke Owen held his mistress Lyra by the waist, smiling sweetly at her. Lyra blushed happily and leaned her body against his chest. The surrounding nobles watched with a mixture of envy and ridicule. Standing just beyond them was the Duchess—Guest. No one even tried to look her way. Two years since their marriage. Her husband had never once loved his wife.

"I should stop expecting anything now."

Muttering this, Guest left the ball. On her way home, in a dim alleyway, an old witch smiled defiantly. The witch held out a small red vial.

"—It's a love potion. Just one drop, and whoever drinks it will be obsessed with you." Guest stared at the vial, and a faint smile played on her lips. What dwelled in her eyes was not sadness, but a quiet sense of mischief.
