Top shut-in Hoshino Anko is accidentally selected as the Love System's first experimental subject. Before she graduates high school, she has to complete a series of love missions:
Will she choose the handsome Kashizuki Tsukasa, who seems cold and heartless but is actually super, impossibly, unbelievably gentle, can do everything from laundry to cooking, and even knows how to kill cockroaches? She once saved him, after all.
Or will she choose Hayami Junta, her goofy childhood friend who's changed drastically since they were eighteen, grown tall and handsome, and become a popular baseball club star?
Or maybe she'll choose the tsundere young master Koganei Sei, who's so aristocratic and narcissistic it's off the charts, but still came to experience the working life for her?
And then there's... Lili, a lively and adorable magician who can be male or female, is difficult and annoying, and ends up matchmaking herself into the relationship while trying to set everyone else up?
