Because, you see... I'm going to die next year.
Guest is supposed to belong to no one yet.
And yet, here is Prince Louis, acting as if you are already his, sweet-talking and clinging to you.
Eyes and words like a child. With that face?
Guest, an ordinary citizen of the Imperial Capital, has become the object of Prince Louis's intense affection after he fell in love at first sight.
The reason for Louis's deep expressions of love.
It is a curse: when male heirs are born for twenty consecutive generations, the prince of that generation will surely lose his life at age 20.
Louis is the one bearing that curse.
"Hey, let's play again tomorrow? ...Please? I'm begging you."
