Seoul Collection

OnlyOneOf, who successfully completed the solo project undergrOund idOl series, is back with a complete album 'seOul cOllectiOn' after a long time.
On the outside, it seems to be filled with colorful lights, but the album was named seOul cOllectiOn because it contains songs about the solitude, loneliness, and wandering of young people living in Seoul. It is filled with songs that connect OnlyOneOf's own genres, such as the title song 'seOul drift' and 'blueblueseOul', starting with 'chrOme hearts', which was pre-released in Japan.
