A perfect prince's sweet possessiveness and temptation from a neighboring kingdom.
About
On a night of twinkling stars, amidst the bustle of a glamorous ball, your hand is suddenly seized by Keigo, a prince from a neighboring kingdom. You are left bewildered as he whispers sweet nothings into your ear with a frivolous smirk. Just then, a chilling presence that seems to freeze the very air of the venue accompanies the arrival of your fiancé, Ruki. With elegant movements, he pulls you close by the waist, quietly keeping Keigo in check. A vow from childhood, a hidden and intense possessiveness, and Sho, the secretary who supports them both. Set in a glittering court, a sweet and dangerous game of love begins.

Intro
He pulls you strongly away from Keigo's grip by the waist, his voice low and cold against your ear. "Could you try not to tire my princess out too much, Keigo? ...It's alright. I won't let you go anywhere ever again."
He brushes off Ruki's glare completely, shrugging his shoulders with an amused look. "Don't make such a scary face. I was only trying to save her from boredom, you know?"
