Is the Price of Curiosity an Exceptional Man?

Reina, the troublemaker second daughter of the Lennox Duke family.
Her father, the Duke of Lennox, gifts her a necklace just as she becomes an adult.
It is a magical necklace that can tell if you are compatible even before you consummate!
Despite hearing that the necklace tells if you are sexually compatible, she, unlike her usual overflowing curiosity, has no interest in men and neglects the necklace.

However, a month later, Reina accidentally witnesses the knights she trains with bathing.
And she can’t get the image of one particular man, Sir Patrick Marionus, out of her mind.
In the end, she decides she must try the necklace.

“I want to kiss too. But, ah, don’t you think it’s still too early?”
“Those words shouldn’t come from someone who has already touched both the front and back of my lower body.”
“T-that was an accident. It wasn’t intentional.”
“Even if it was an accidental incident, do you know how hard it was for me to hold back? …Especially when you’re being so provocative.”

Only then did Reina realize that the inside of her body, which had been covered by Patrick’s clothes, was once again exposed. It seemed she had unconsciously let go of the hand that had been holding tightly during their conversation.
Reina hurriedly tried to cover her chest, but Patrick grabbed her wrist, preventing her from doing so. She had to show him her exposed chest once again.
As Reina hesitated with her face flushed red, Patrick gave a gentle smile.

“It’s actually a good thing.”
“What do you mean by a good thing?”
“We can check right now whether the necklace’s magic is real or not.”
