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?

Confessing your love for someone can be very tricky... and it's not any easier for Yukino!

A new boy has just transferred to Yukino and Arima's school... Asaba. He's pretty handsome and charismatic, so it doesn't take long for him to rise in popularity, but he's got a real problem with Yukino.

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...

The class has sided with the scheming Maho and they all decide to give Yukino the "silent treatment." As time goes on and it appears that things won't change, Yukino knows that she'll have to confront her saboteur and put an end to the harassment... but how?

Summer has arrived and it's a time of separation. Arima is going away for a Kendo tournament while Yukino has made new friends. Even Tsubasa has taken a liking to Yukino, but something's not right... she's grown a little too attached.

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.

Arima's absence has been hard on Yukino, but she's not the only one. Asaba's had it tough as well...

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.

Arima's feelings for Yukino are beginning to build up and he knows now, more than anything, he wants to take their relationship to the next level...

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!

Tonami had a tough childhood... he was constantly sick, being bullied, but the worst of it was all Tsubaki's fault. Now he's back and he's determined to throw it back in her face!

Aya has finished her script for the culture fest play, but neither Yukino nor Maho are eager to participate. All the while, Tonami has begun to make his mark on Tsubaki. She begins to suspect who he really is.

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

Yukino's organizational talents shine as the play really starts to come together. Meanwhile, Tonami's plot for revenge against Tsubaki isn't going as well as he'd hoped...

Yukino has changed a lot since meeting Arima, but Arima still feels that he himself hasn't changed much at all.

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

The final episode. As tensions rise over Arima's jealous and over-protective nature, Tonami begins to realize that his desire to get Tsubaki to notice him was one born out of an emotion different from hate.
