"Please! I'll do anything, just pretend to be my fiancé for three days!" Akari-senpai is an incredibly beautiful but strict and scary female boss. "You're sloppy! You lack hygiene! You're incompetent!" I'm scolded by her every single day (cry). One day, to avoid an arranged marriage set up by her parents, Akari-senpai orders me to play the role of her lover in front of them for three days. "A single futon," "kissing in front of them," "stamina-boosting meals," and "sexy lingerie"—her parents, eager to see their grandchild's face, set various "breeding traps." I try to get through it with acting, but eventually... An unexpected three-day lover life with my scary but beautiful, longed-for female boss!? "Senpai... your parents are listening, so even if it's just acting, we have to have sex!" "You are absolutely not allowed to insert!" "Can I just insert the tip for the sake of realism?" "Geez! You're getting carried away!" "It's just acting, so don't swing your hips so much!"
