Mtiful Day is a rock duo consisting of members Choi Wan Joon and Yoon Dong Ha. The duo began their activities as an indie group back in 2000 and they recently signed with their first music label, Starherb Contents Media. With this signing, the boys released their debut EP titled "Love Potion" earlier today. The EP contains a track titled '??? / Ttu Ttu Ru' and the MV was released in conjunction with the EP. The track has very CNBLUE-esque vibe to it and the MV features a Vampire concept. This group has some talent and potential, the track is very easy to listen to... but the MV is a bit cheesy. The boys are scheduled to make a performance on Music Bank so keep an eye out for it. Check out the MV below and remember to support them by purchasing the music. Tip: Kang Mi
