Todokanai Koi '13' (届かない 恋 '13')

"Todokanai Koi '13' (届かない 恋 '13')" is performed by Uehara Rena and was used as the first opening theme for the 2013 television anime White Album 2 (WHITE ALBUM [ホワイトアルバム] 2). The song accompanied Satelight's adaptation of the series and introduced its romance-and-music setting at the start of each episode.

Musically, the track is presented as polished J-Pop, built around a controlled verse and a chorus that opens the melody into a more expansive emotional register. Uehara Rena's clear, steady vocal delivery keeps the song poised, giving the opening a wistful tone without pushing it into melodrama.

That balance fits a story centered on a light music club, performance, and complicated relationships. As an OP 1 for White Album 2 in 2013, the song frames the anime's mix of youthful ambition, loneliness, and romantic uncertainty in a concise form that connects directly to the series' emphasis on music.
