I did my best for my little sister—but I’m done now, big sister quits!

Sherry devoted her life to her younger sister, her only remaining family, after the girl was chosen as a Saint. Determined to stay by her side, Sherry worked tirelessly to become her exclusive gatherer, searching day and night for rare medicinal herbs and special magic stones—all for her sister’s sake.

But when her sister comes of age and gets engaged, she coldly tells Sherry,
“I hate you. Get out of my sight.”

Heartbroken, Sherry decides to leave the kingdom.

“If you become my exclusive gatherer, I promise to treasure you.”

On her journey, she meets Aslan, an unbelievably handsome mage who earnestly asks for her services. In an instant, Sherry’s life—once filled with nothing but endurance and self-sacrifice—changes completely!?

Surrounded by a princess-like lifestyle, Sherry is bewildered, yet gradually begins to fall for Aslan, who truly cherishes her for who she is.

“Maybe… it’s okay for me to be happy too.”

Thus begins a Cinderella-style comeback story of a genius gathering otaku turning her life around at last!
