Ha-on Kim released a new album 'i+em'.

In the album introduction, there is only one short English phrase, replacing the letter t with '+', just like the title.

The lyrics of all 12 songs, from 'Shot Caller' to 'Viva La Vida', were written by Kim Ha-on himself, and he also participated in composing all of the songs.

Ninetyniine, brendontleave, Teyung, and EF were responsible for composing and arranging each song, and all songs were recorded in Los Angeles.
