All of Minseo's first mini-album [The Diary of Youth] have been released. 

MINSEO, who sequentially released 'Without Knowing' and 'Is Who', starting with 'Wonderful Dream' in March last year, completed his debut album with the last song '2cm'.

The title song '2cm', which will mark the end of the album, is a thrilling duet song that compares the close distance between two people right before falling in love to '2cm', featuring singer-songwriter Paul Kim with a sweet tone. The tender voices of the two on top of the soft melody delicately capture the delicate emotional lines just before falling in love, making the listener feel moist throughout the song.

Minseo's debut album, with the theme of 'girl's growth', unravels various emotions that a girl who has just begun to know love, such as fresh excitement, growing pains, and awkwardness, can be felt in different genres and concepts. It contains the image of Minseo growing up one by one. 

In Minseo's debut project, talented composers such as Lee Min-soo, Park Geun-tae, Jehwi, GDLO (Monotree), and Aurori participated to make use of Minseo's colorful voice, and lyricist Kim Eana wrote lyrics for all four songs to create a girl's growth story.

Producer Cho Young-chul, who has presented unique concepts and trends with IU, Brown Eyed Girls, Ga-in, and Uhm Jung-hwa, is in charge of the overall production of the album.

MINSEO, which showed its ever-changing charm through its debut album, plans to unfold a more mature sensibility and expanded musical spectrum in the future.
