Background
The song was written by Shizuka Kudo, under the pseudonym Aeri, composed by Tsugutoshi Gotō and arranged by Draw4. Kudo revealed the origin of her pseudonym when she was interviewed as a guest on the Fuji TV music show TK Music Clamp, stating that Aeri is what her mother had considered naming her and she had felt it fitting to use it as her lyricist pseudonym. Lyrically, "Senryū no Shizuku" deals with the theme of forbidden love. The track was praised for its "modern and chic" melody and "delicate" lyrics. Music critics also noted the influence of Miyuki Nakajima's work on Kudo's first forray into songwriting.

Cover version
In 2014, Tomomi Kahara recorded a cover of the song for her album Memories: Kahara Covers. While promoting the album, Kahara performed the song in duet with Kudo on the music show Music Fair.
