It’s a song that vividly portrays a hopeless love—one where the narrator, fully aware they’ll never be “the one,” continues a relationship in which they’re called on only when convenient.

Released as the B-side to back number’s 2012 single Aoi Haru and later included on the album blues, it depicts a protagonist who sarcastically acknowledges settling for an ambiguous relationship yet can’t stop the feelings that grow with every time they sleep together.

The fear that putting it into words would break everything keeps them swallowing the decisive confession, a detail that feels painfully real.

The groovy sound—highlighted by what Iyori Shimizu has called the standout bass line before the second chorus—is another draw, and the song became so beloved by fans that it even spawned a sequel, Supporting Actress Syndrome 2.
