Saku (EP)

Saku is the second Japanese extended play by South Korean singer Onew. It was released on October 1, 2025, through Victor Entertainment. It contains five songs, including the lead single, "Hana no Yoni".

Composition

The Japanese word saku means "to bloom", and each of the EP's five tracks contain stories related to flowers. Onew said he chose the title to reflect how life's happy moments can bloom like flowers. The opening song, "Kimi=Hana", describes the colourful flowers that bloom in each season. Lead single "Hana no Yoni" expresses fond memories of a lover. "Lily" describes driving along a highway at night after fighting with a romantic partner. In "Beautiful Snowdrop", Onew fantasises about the object of his affections. The final song, "'Cause I Believe in Your Love", is about a promise to meet again one day.
