Love Lab is set in Fujisaki Girls Academy, which is known for their school body being composed of very proper students. The most prominent one of them is Natsuo Maki, the student president who is admired by her classmates for her calm and polite demeanor. On the other hand, Riko Kurahashi is also admired but for having a very forward and boyish personality. Riko accidentally walks into Maki when she is kissing a body pillow with a picture of a guy for practice, and learns that she is not as collected as everyone thinks she is. Riko is forced into keeping Maki's secret and joins her in practicing romance activities such as holding hands and more.
Episodes
The second-year student of the distinguished Fujisaki Girls Academy Kurahashi Riko is known by fellow students as a wonderfully wild girl and is also known as "the Wild Kid." One day, Riko witnesses the unladylike behavior of the lovely and academically successful student council president Maki "Miss Fujijo" Natsuo.
Student council secretary and first-year student Tanahashi Suzune witnesses all the details of Riko and Maki's love lab. Believing she has been scorned by Suzu, who fled the scene in a hurry, Maki is shocked.
The ones harassing Riko and her friends were "former" student council president Enomoto Yuiko (Eno), whose work was stolen by Maki, and her friend and student council treasurer Mizushima Sayori (Sayo). Declaring war on Riko and her friends, Eno and Sayo sneak into the student council room where they discover materials related to the love lab. Meanwhile, Maki takes on all the responsibilities of the student council herself and collapses from the strain...
Eno becomes the student council vice president and Sayo becomes the treasurer once again. The five members of the student council are as eager as ever to resume their love lab. Riko breaks into a cold sweat when the other members begin treating her as their master of love after she blurts out a lie.
In order to respond to the request for romantic advice left in the suggestion box, Maki and Eno take over the broadcasting room during lunch and begin a special student council broadcast. Maki and her friends have prepared a strategy for responding to the anonymous girl asking for advice at Fujijo, a school that forbids romantic relationships.
Riko heads to a shopping mall after school where a boy suddenly calls her by name. While pretending to remember who he is, through their conversation Riko discovers she once rejected him.

When Nana takes photographic evidence of Sayo meeting her boyfriend, the school finds out. Sayo informs Riko and the others of her decision to quit the student council. Unable to accept the situation, Eno announced to Sayo she will fight back for her.
Sayo's punishment is repealed, and the student council room returns to normal. Riko and the others make Sayo try on all kinds of disguises so she can go on dates in peace, but soon they begin criticizing the clothes she wore on her date...
A note asking for hairstyles popular among boys is found in the suggestion box. In order to fulfill the request for the opinions of boys from Southern Middle School, Riko searches her cram school for boys from Southern Middle School and comes up with Nagi.
