Days of Labyrinth.The school's Sports Fest has been taking up all of Yukino and Arima's time, making it so that they don't see each other at all for two days. Finally they pass each other while running to do some tasks for the festival. Being stressed out, Arima yells at some guys that were asking them for help. Then, Arima and Yukino go to the roof. It's awkward at first, but they then talk. After a comment that Yukino says, Arima makes a distracting comment of the weather and ends up kissing Yukino on the cheek. He then leaves to go back to work again. After a while, Yukino notices Asaba Hideaki. Since he's friends with Arima, Yukino tries to befriend him, but all Asaba does is be rude to her and walk away. This leads to a lot of fighting between the two of them. Arima also later asks Yukino on a date. While Yukino is walking in the hallways, she bumps into Asaba who tells her that he wants to use Arima as his partner to get girls and ends up making her feel bad. Arima, who knows what Asaba had done, later gets Asaba by the shirt and tells him that he's wrong. While Yukino is getting stood up by Arima, she bumps into Asaba who apologizes to her. He then tells her that he might even like her. Arima then comes sprinting to Yukino and explains to her that it was his mother. Asaba then grabs Arima and tells him to apologize but Yukino stops him. Asaba ends up joining their group.
