From I''s: Mou Hitotsu no Natsu no Monogatari - Season 1

* Based on the popular manga by Katsura Masakazu. Itsuki, a childhood friend of Ichitaka, who aimed at becoming a molding artist and went to America, comes back to Japan to meet up with an old childhood friend of hers and Ichitaka's. Nearby Iori is having a photoshoot and Ichitaka is riding his bike. Soon, the girls end up in a pinch... Note: The anime is a sidestory from the manga; it's a good idea to read the manga before watching the anime but it isn't necessary to understand the "plot". (Source: AniDB)
