Koi no Iro wo Oshiete.

High-school senior Chihiro is attracted to Ayuta, another boy at his school, but Ayuta only has eyes for his childhood friend Hayato, even though he knows Hayato already has a girlfriend. Ayuta continues to play the role of a devoted friend, but the anguish that shows through on his face from time to time only serves to pull Chihiro even closer... It may be too soon to call these pent-up feelings crying out from their hearts "love", though.... It's a youthful, lyrical lovestory between two immature and uncertain high school boys.
