"If it's only for three seconds, it doesn't count as cheating!"
The moment I got a girlfriend, my tsundere childhood friend Mia, who was suddenly jealous, pushed some mysterious rules onto me!
"You're a virgin, right? You need to practice kissing and sex, or else it'll be too bad for her!"
Every day, I'm forced to spend time with Mia, who claims to be experienced, and the short-time sex that doesn't count as cheating if it's only for three seconds keeps escalating!
