Kotoko, from the lowly F-Class, has a crush on Irie, who is the top-ranked student from A-Class. After two years, she collects her courage and confesses to him and tried to give him a confession letter, only to be bluntly turned down. Irie even goes so far as to say he hates stupid girls (meaning her) and doesn't even read her confession letter. When an earthquake strikes Tokyo, her house is the only one damaged. A friend of Kotoko's father jumps at the opportunity to lend a hand, and in a surprising turn of events they end up living at Irie's house.

Yes indeed, it is the renown Irie-kun's house. After some small talk at breakfast Kotoko and Irie are pushed out the door by Irie's mother,and on to school they walk together. But not happily. Irie-kun soon shows how much he doesn't care for Kotoko-chan, or maybe how little he care for human decency. While riding the train Kotoko-chan get's pushed off at the wrong station by the crush of the crowd. When Kotoko frantically tries to get on the train, the doors close and Irie-kun watches as the train slowly pulls away from Kotoko-chan, leaving her with the only options of running to school or being late. When Kotoko-chan confronts him about his rudeness he simply says for her not to talk to him and that he hates absent-minded girls more than stupid ones. After dealing with all of Irie-kun's cold disdain, she decides to one up him in the upcoming exams.

After Kotoko-chan and Irie-kun had gotten just a little closer, she inadvertently brings embarrassment to the one she loves. Now he will never love her. She falls asleep with tear-stains down her cheeks and her confession letter in her hand. When Irie-kun walks into to tell her it's her turn in the shower, he on impulse decides to read the letter, his face is blank, and void of expression. At breakfast the table is full of talk of the Sports Festival. On a whim the family decides to watch as Kotoko-chan and Irie-kun participate especially since they happen to be participation in an event together.

Geez, Irie-kun's mama is really determine! Kotoko-chan and her friends have made plans to go to Waterland and (only thinking about Kotoko and Irie-kun's future) she sends Yuki and Irie to Waterland just to try to get Kotoko and Irie into a romantic sitsuation! Yeah I know, but anyways on their little trip Yuki tries to observe Kotoko at a closer view, so he asks Irie to go get him some icecream. While Irie's out, to get Yuki's icecream, Yuki switches from the part of the pool where he can stand on the floor , to the part of the pool where Kotoko and her friends are.(where he can't stand) Right when he let's go of the ladder he starts to sink because he can't touch the bottom. Right after he become unconsious Kotoko saves him! During that time, Irie over hears these two girls about a little kid who almost drowned! Next, after he heard he hurried off without the icecream to see if Yuki was okay. When he finally gets Kotoko and the others, he realizes that Kotoko took very good care of Yuki, so he just stands there and smiles! Soon after that Kotoko decides to take everyone to the Waterslides and when its her turn to go down she goes. Once she starts going down, she gets a leg cramp, which paralyzes her so she can't move! Once she get to the bottom of the waterslide, Irie notices that she's having a hard time getting out, so he pulls her up and out of the water just in time, and gives her foot a relaxing foot rub!

The final exams starts next week, and the results decide whether or not the F-class students make it into college. After having recieved prior assistance from Naoki with her and her friends' schoolwork, Kotoko is asked - commanded, rather - to get Naoki to tutor the whole of Class F so they can pass their finals.

With Naoki's help, the whole of Class F passes their finals (with the exception of Kinnosuke.) Kotoko tries to give Naoki some homemade chocolate but fails to do so. Later on, Naoki is set to take the entrance exam to Tokyo University. Kotoko sets off to accompany him to the venue; however, the plot twists when Kotoko's health takes a turn for the worse.
