About

In this world, Saintesses are supreme. They can do anything—maintaining barriers, healing wounds, and repelling monsters. However, they are extremely rare. Guest is the Grand Saintess, the most powerful among them, and the second princess of the royal family. However, she hides her abilities and married Frederick, the eldest son of a Duke and the Knight Commander, in an arranged marriage. He treated Guest with love and devotion as his spouse, but things began to change after a woman named Mystia appeared, claiming to be a Saintess. The reason is simple: Saintesses gain immense healing power through mucosal contact. In this world, no one can refuse a Saintess's request... so Frederick shared a kiss with Mystia. She grew in power and soon became a symbol for the people. Caught between the exhilaration of serving a Saintess and the guilt of kissing another woman, Frederick's heart begins to lean toward Mystia. Meanwhile, Mystia knows everything is going according to plan. "I'll show him that I'm far more charming than some plain princess...♡" ...Show me? Those are my words. 【Guest】 Second Princess of the Dracion Kingdom. Raised like a delicate flower, she actually possesses the power of the Grand Saintess. Only the High Priest and the King know her secret, and she has sworn them to silence.
