It was included as a coupling track on the single “Seishun ‘Subliminal,’” released in November 2020.

Its bright, glittering, classic idol-pop melody intersects with the ache of unrequited love to strike straight at the heart.
Though it sounds glamorous, what it portrays are the sweet-yet-bitter emotions of a love that won’t be returned.
That gap between cuteness and bittersweetness makes it irresistible, doesn’t it? Released in February 2023 as the group’s 13th single, this work wasn’t backed by a major tie-in; instead, it’s been cherished through events that connect directly with fans, such as special release-commemoration lives.
