Kihyun of the group MONSTA X joins the OST lineup of the drama "Welcome." Kihyun will release OST Part.7 "Spring, Again" of KBS2's Wednesday-Thursday drama "Welcome" on various music sites at 6 p.m. on April 9. "Spring, Again" is a song that expresses a man's mournful heart that he cannot let his loved one go even if warm spring comes after winter, adding to the calm, beautiful piano melody and the sound of a grand orchestra to the sad tone of MONSTA X's main vocalist Ki-hyun. As Ki-hyun is an explosive singer and has delicate emotional expression, it is predicted that he will be able to maximize the immersion of the play with his appealing vocals.

In particular, the song's lyrics include the winning song that passed the 2000:1 Lyrics Contest held last month, adding to the speciality of music fans' curiosity.
