Earlier today, neo-urban sound group One Way made a digital release of "Rainy Days" on Korean music sites, marking their official comeback since their debut 10 months ago. The official music video to the song was finally unveiled through their official YouTube channel.  The music video perfectly showcases the trio's talent against a dark, abandoned building that fits well with the song's overall gloomy lyrics that expresses the sorrow of a man that has lost his love.  The addition of the vocals and appearance of 2PM's Junsu adds a special finishing touch. Their full album also features a variety of guest vocals such as J and As One.  All 10 tracks included in the album were composed, written, and arranged by the trio and offer a variety of genres such as R&B, electronica, swing, and ballad, all the while using hip hop as its base.
