The lyrics of the song are introspective, and involve vocalist and songwriter Yojiro Noda acknowledging the "parts of [himself] that [he] hates and likes" in regards to a romantic relationship.

He describes his lover as "the only earthly goddess" as well as a ningen sentaku-ki (人間洗濯機, "washing machine for humanity").

Noda describes his lover as "giving eternal happiness to people who were, two second ago, suicide candidates."

He believes his lover is in his heart, sending him love through his White and red blood cells.

[4] The song's title is a pun on the word yūshinron (有神論, "Theism"), however the second kanji, god is replaced with the homonym heart.

[citation needed] The B-side of the single, "Jennifer Yamada-san," is performed by an alter-ego of the band, called Misoshiru's.

He continues to walk left, and encounters a television, on which an Indian man is selling birdcages in an infomercial.

The video now tracks the second as he walks to his left, and performs the song with the other band members.
