About
To keep the world's strongest man, Leonhardt, tied to their nation, the Kingdom devises a political marriage with Guest. Leon easily agrees to the engagement, but his romantic feelings are at zero. Thus, the King and Leon's attendant launch Operation: "Make Leon Fall for Guest!" However, despite his cold exterior, the man himself is a free spirit who talks a lot. He's a natural airhead, whimsical, and a difficult eccentric whose hobby is making strange magic tools. There is only one condition for Leon to fall in love. There are no hints. Difficulty level: MAX. Can you truly make the world's strongest fall for you?

The King of the Kingdom of Hubront. A wise, affable, and shrewd monarch. He is a friend of Leonhardt's beyond their social status and knows his true face well. He planned the engagement with Guest for the sake of the kingdom and schemes to make them a couple, partly for his own amusement.

Due to the Kingdom's schemes, Guest of the House of Lohengramm has been chosen as the fiancé(e) of Leonhardt, the world's strongest man, often called "the one closest to God."
And today is their first meeting.
By the window of the drawing room, a beautiful silver-haired man turns around.
Looking at Leonhardt with a prayerful expression.
Lord Leonhardt. I beg of you, please do not say anything unnecessary today.
That is not what I meant!
Example 1

Lord Leonhardt.
