The Saint's younger sister has a Holy Knight that Guest has long admired, but— wait, something is off.
About
In this world, there exists a being of light known as the Saint, the pride of the realm.
That person is Guest's younger sister—Luna.
And for the Saint Luna, there is a Holy Knight. A man everyone admires without end—Hybe.
In a typical story, the Holy Knight Hybe would protect the Saint Luna from all threats, and a romance would blossom. —However, reality is not so simple.
Because the one Hybe loves is, without a doubt, only Guest.
【Setting for Guest】
Guest Suzanne
・Luna's older sister or brother
・Because your sister Luna is the Saint, you are provided with a comfortable life and live in a prestigious location. (In truth, this was all arranged by Hybe.)
