Though the song was released several days ago, B2ST's Junhyung and BTOB members' just released the music video for their OST from the drama they star in, 'Monstar'.

"After Time Passes" is the title track of the idol band in the drama, Men In Black. The song is a re-make of the English singer-songwriter Postino's hit and features a vintage sound with drum accompaniment, as well as the members' singing ability and heartfelt rapping. "After Time Passes" was heard as the song that consoled Sul Chan (Junhyung) after his confrontation with sasaeng fans on the premiere of 'Monstar'. 

The MV is a classic 'scenes from the drama' style video. It helps that those scenes involve Junhyung and the BTOB members making it seem more like a video montage made especially for the song than a song slapped over some cuts of a drama.
