On the first day of high school, Yuki is not perfectly happy as she failed to get the highest score at the entrance examination. Although she does not show her desire, she wants to be the center of attention always. The honor belongs to her classmate, Arima. Yuki feels strong rivalry to Arima. She beats him at the mid-term exam. To her surprise, Arima congratulates her achievement heartily. One day, Arima tells her that he wants to “go steady” with her. Yuki bluntly refuses his proposal. Then, she accidentally reveals her true desire and is terrified by her mistake.

Yukino's inadvertently made a fool of herself in front of Arima and now he's blackmailing her! Getting her to do his work, act as his slave... she's just about at her wit's end!

Things have been good between Arima and Yukino for the past few weeks but lately Arima has been acting strange. He's been very distant and it almost seems like he's purposefully ignoring Yukino... what is it that's changed so suddenly?

Arima and Yukino lead very similar lives despite their differences... but how will their bond stand against the test of time? While Yukino feels as if she's been liberated of her guise of perfection.

The newest test scores have been posted and Yukino and Arima's scores weren't up to their typical standard.

Arima and Yukino both have the day off from school so they decide to meet up over at Arima's place. But that's not the whole story...

Two jealous rivals emerge to sabotage Yukino! The first girl, Maho, resents her popularity and attempts to unmask Yukino's superficiality to the whole school...

Tsubasa has holed up at Yukino's house and refuses to go home. Tsubasa's father is remarrying and it's been hard for her to come to terms with the idea.

Tsubasa decides to go home, but her loathing for her father getting remarried is renewed upon meeting her future stepbrother... a punk-rocker named Kazuma. How could she ever possibly relate to someone so completely different?

Yukino and Arima's story up to this point is revisited.

The Miyazawa family heads off to meet grandpa... an ill-tempered old man who's got it in for Yukino's father!

Hearing from her friends that Arima has changed a lot over the summer, Yukino bemoans over the fact that she hasn't changed at all and that she can't seem to get her feelings sorted well when it comes to him.

Yukino isn't all that interested in the culture fest until she finds out that the class that puts on the best show gets the test notes of a student who went on to Tokyo University!

After reading the Aya's play, Yukino decides that she'd like to participate in it.

Kano's been feeling a strange presence lately... as if someone is following her. Mysterious phone calls... flowers from an anonymous admirer...
