Active in F.T. Island’s Subunit F.T. Triple

Following the popularity of F.T. Island, FNC Entertainment decided to make a subunit of the original group named A3. It consisted of Lee Jae-jin, Choi Jong-hoon, and Choi Min-hwan. The name came up as a result of the fact that the three of them had ‘A’ as their blood type. The subunit made their debut in January 2009 through their performance in the My First Dream new year concert which was held in Japan. Basically, the subunit A3 was made with the purpose to take up some singing parts during F.T. Island’s concerts. It was also meant to help the main vocalist Lee Hong-ki to not overstrain his voice. In A3, Jaejin was in charge of the lead vocalist and bassist position, but eventually, he ended up working more with the guitar. The name A3 was changed in the late 2009s, and became F.T. Triple afterward. The group released the hit single “Love Letter” and went to several music shows to perform as well. One of the best live performances of F.T. Triple was in Music Bank where the three of them sung “Love Letter”.
