'Rookie Employee' is a thrilling and thrilling office romance between part leader Kim Jong-chan (played by Kwon Hyuk), a perfect man with the top sales in the advertising industry, face, and body, and Seung-hyeon (played by Moon Ji-yong), a new employee who is new to everything.

The OST track consists of representative songs 'What's wrong with me' and 'IoU' and four background music, and also includes unreleased special videos by director Kim Jo Kwang-soo and actors Kwon Hyuk and Mun Ji-young.

"Can't I help being attracted to you?" The main theme of "Why are you doing this to me?", which sings the feelings of being attracted to each other, expresses the pounding heart with the lead and guitar, with the EP sound as the main axis. The horn session heard after the bridge heightens the emotions of the actors, and the calm voices of the two actors (Kwon Hyuk and Moon Ji-yong) tell a story full of sincerity. In addition, the vocal version of Cho Ji-hoon is included to give a deep sense of nostalgia.

The main theme 'IoU' is a medium-tempo pop-style song that expresses the puzzling feelings of both my heart and the other person's heart when love sprouts with a refreshing rhythm. IoU is a value representing the degree of agreement between two sets as a value between 0 and 1. If there is a part that intersects between people and love other than the part that was alienated, it would be good to focus on that relationship to some extent from now on.
