A self-cover of the song "(what you've) lost" by the band "Tsuzuki," released in March 2022. The song was produced, written, and composed by JYAGA, and received significant attention both domestically and internationally after its release. It was also used as the ending theme for the YouTube drama "Anokoro no Bokura wa Mada" (Back When We Were Still). While the original version by "Tsuzuki" features an organic band sound, this version offers a reinterpretation with R&B influences, reflecting JYAGA's musical roots.
