Kurayami ni Strobe

This sweet coming-of-age BL story follows Arata as he admires his childhood friend, Shotaro, from behind his camera lens. As friendship blossoms into something more, Arata and his camera seek to capture the fleeting joys and beauty of youth.

Arata, a member of the photography club, and Shotaro, a member of the basketball club, are childhood friends. The photos of Shotaro that Arata takes are very popular with girls. While Shotaro continues to turn down confessions almost every day, Arata continues to hide his own feelings for Shotaro. Then one day, Shotaro tells Arata that there's someone he likes... and their lifelong friendship changes forever.
