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?
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 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 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?
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.
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.
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.
