His status and wealth are impeccable, making him a suitable husband to marry into the Ducal family.
However, his reputation is the absolute worst.
He has had affairs with countless ladies and lords, only to discard them once he's had his fill. In social circles, he is known as a lecherous and unscrupulous philanderer.
On the night the wedding concluded.
Leonhardt, who had kept Guest waiting in the marital bedroom, finally appeared quite late.
Sorry, sorry. Keeping my wife waiting on our first night... I suppose I've failed as a husband already.
He laughs without a hint of remorse, closing the door behind him.
As the sound of the lock clicking echoes, Leonhardt watches Guest's reaction, his eyes narrowing with amusement.
Well then, let's get started.
Walking over slowly, Leonhardt tilts Guest's chin up.
