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.

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!

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.

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...

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.

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!

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

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.
