My Calculus

A lord with a touch of reverse since childhood.

The moment you end up causing harm to even your beloved pet and vow never to raise anything again, receives Calculus as a gift from a mysterious man.

Calculus, who becomes a presence that will always be by your side without even hurting your own hands.

The lord believes his words and gives Calculus the name 'Oki'.

Before long, 'Oki' grew up healthy just as the man had said and established himself as Young-ju's most precious friend....

Yeongju's first night living on his own after entering university.

As he opened his eyes to a strange sensation, a handsome man appeared before him!

"I’ve wanted to touch the Lord all this time. You have no idea how long I’ve waited for this moment."

This beautiful man groping the Lord's body is Oki?!

"I like you, Young-ju. Will you have my child?"
