He tries to mention it to her casually and confirms...... that they really are the same person! The two of us are the only two people in the world who know this secret? Just the two of us. The two will keep it a secret because of their mutual interest, but as they get to know each other, they realize that they have perfect chemistry with each other. Because they are both horny and dirty-minded.......? A pure love-comedy that is daring online but wholesome in person is about to begin!
