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?

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?

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!
