"Cheating doesn't count if it's only for 3 seconds!"
My tsundere childhood friend, Mia, who became jealous as soon as I got a girlfriend, suddenly approaches me with mysterious rules!
"She's a virgin, right? She'll feel bad if she doesn't practice kissing and sex!"
As Mia, who claims to have a lot of experience, hangs out with her every day, the short 3 seconds of sex that doesn't amount to cheating quickly escalates!
