When young Kotoko-chan, in the unintelligent F-Class, places her heart on Irie-kun, the top ranked student from A-Class, is it all for naught but pain? She finally, after many years, collects her courage and confesses, only to be torn down. Irie-kun even goes so far as to say he hates stupid girls (meaning her), he doesn't even read her confession letter (which she poured her heart into so sweetly)! Will this one sided love continue in this adversity? And what's this, she already has an extremely passionate admirer, Kin-kun? Yet poor Kotoko-chan's day is not over. Tonight is the night she moves into her new house! Oh, the embarrassment though when a slight earthquake tiptoes through Tokyo, her house is the only one to have damage done. Oh, and how extensive it is! The house crumbles like a card pyramid. Now Kotoko-chan is without heart and home. Good thing her dad has a very hospitable friend that jumps at the opportunity to lend a hand to this family. But wait, his name is Irie-kun. It couldn't possible be that... They are staying at Irie-kun's house! What a twisted love chain it has become, and only the first episode!

Yes indeed, it is the reknown 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 upcomming exams. While studying at the house Irie-kun's mother shows Kotoko-chan pictures of Irie-kun's sister... what!?!? Irie-kun was dressed as a girl, and a cute one at that. With one cute picture in hand and a dasturdly plan she cohoces Irie-kun into becoming her tutor for the exams. On the condition that she make it into the top 50 sudents with the highest score, she 'll give the picture back. He grudgingly accepts and a truce is born. While studying the intense stressful attitude turns slowly into a less tense good natured bit of bullying. There are even a few times when they fall asleep charmingly after studying late into the night. On the way out the door Irie-kuns mother happily gives Kotoko-chan and good luck charm for the test and the two student head to school. Poor Kotoko-chan though, she clumsily misses the bus again, wait ... Irie-kun put his hand infront of the door this time. Something must really be changing. Irie-kun might have a soul. Also, as they walk to class he say's "good luck". the test is over, results are in, and Kotoko has made it at spot 50! She remember's the goodluck charm and opens it to find an uber cute picture of her and Irie-kun asleep while studying. Her friends find out and even though they promise not to tell about it, Irie-kun is teased about it somehow and angrily tells Kotoko-chan to stay out of his life!
