The truth of a "man who just wants to fuck" and a "tomboyish woman" that can only be seen because it's a hidden camera recording. Yu, a 24-year-old office lady. "I just can't act girly lol," she says self-deprecatingly, but the man follows up and they get intimate! Even to the man's negative comments, she says, "Alright, I'll listen to you!" and releases her maternal instinct, patting his head. The man naturally misinterprets this and kisses her, to which she replies, "Who are you!? //" While blushing, she goes full "big sister" mode and takes the lead, saying, "You have to be gentle at first..." A beauty who wouldn't sleep with you no matter how much money you offered, ends up having sex as her maternal instincts are fully unleashed!
