The fourth OST has been released for the underrated gem of a drama that is Secret Forest. I appreciate that the production chose such nice songs for the soundtrack. Every OST released so far was a pleasure to listen to. Like a Monster is a theme song for one of the mysterious characters – Lee Chang Joon, the Deputy Prosecutor, whose true nature still remains hidden. He was once a righteous and just prosecutor that wanted to take the right path and not be tainted by the cruel world, but he made wrong choices repeatedly, got involved with shady people and eventually became a monster. Lee Chang Joon is a very interesting and layered character. He knows what he became and fully realizes that he’s too far gone, but he is a pitiful man with crushed dreams and pride, looking tired of the life he’s leading. Like a Monster is a great theme song for this character, listen to it below.
