The filmmakers behind comedy flick "Twenty" will release songs from the movie's soundtrack featuring the voices of actors Kim Woo-bin and Lee Jun-ho ahead of its March 25 release.

Lee Jun-ho, a longtime K-pop singer with boy band 2PM, will on Friday release an upbeat song about puppy love with fellow actress and vocal music major Lee Yu-bi. The actress previously starred as the romantic rival to Park Shin-hye's character In-ha in hit SBS drama "Pinocchio."

A week before the film opens nationwide, a second theme song will drop on March 18, melding Kim Woo-bin's masculine narrative voice against quartet Sweet Sorrow's mellow vocals in a witty song about life during one's 20s.

Kim Woo-bin stars as mischievous ladykiller Chi-hoo, while Lee Jun-ho acts the optimistic yet luckless Dong-woo, who captures the heart of Lee Yu-bi's So-hee. Kang Ha-neul plays the third main character, studious would-be "good boy" Gyeong-jae.
