A twisted lord is infatuated with a selfless maiden!

I'll make her my confidante!"
Tercio, the son of a lord, falls in love at first sight with Sheila, whom he meets in town.
He half-forcibly summons her to his mansion.
Sheila, who grew up in an orphanage, comes to the manor as a way to repay the orphanage's debt, but she is surprised to find that Tercio, whom she thought was a child, is a respectable young man.
Not wanting to let go of Sheila, Tercio keeps her around and listens to her, wanting to hear about the lives of the townspeople.
Sheila's unexpected genuineness, forgetting the difference in their status, makes her feel at home, and she often comes to the house to talk with him.
The two gradually grow closer.
One day, however, Tercio takes Sheila's lips in a moment of passion, and their relationship changes...!
