Fujisaki Girls Academy is renowned for its elegant and refined atmosphere, boasting Natsuo Maki, the student council president, as the epitome of poise and excellence, revered by her peers. However, Riko Kurahashi inadvertently discovers a different side to Natsuo's persona as she catches her rehearsing her kissing skills on a pillow. Natsuo confides in Riko her yearning for greater romance in her life, and Riko agrees to assist her in her private "Love Lab" research project investigating the subject. As the experiment progresses, student council members join in on the merriment, examining the basics of love and relationships, exploring coordinated "accidental" bump-ins and hand-holding. Love Lab adopts a light and comical approach to illustrate the journey of these thrilling personas as they navigate their way through companionship, love, and the absurd circumstances that confront them at every turn.
