S1·E6 Leap Before You Look

Kafuka comes down with a cold during the summer and has to go see the doctor, Mikoto Itoshiki, who happens to be Nozomu's brother. Later, Chiri and Kafuka find out from Mikoto that Nozomu has gone back to his hometown in Kuraizawa for an arranged marriage. One way or another, the girls somehow all end up arriving at Kuraizawa, where they are taken to the Itoshiki residence by Tokita. Here they find out that the Itoshiki tradition for arranged marriages simply involves both parties exchanging eye contact. The rest of the episode involves Nozomu and his attempts to avoid eye contact with the girls and various other people/objects.
