2BiC has released their new single, "Promise You", which is a love song dedicated for brides and grooms to be, and has announced a contest to go along with the song.

"Promise You" was composed by veteran composers, Cho Young Soo and Ahn Young Min, and its acoustic melody and warm lyrics express the sweet and lovely feelings towards the person one loves.

2BiC is currently holding a special event through which three lucky couples will be chosen to have 2BiC sing a congratulatory song at their weddings. To enter this contest, leave a brief story and comment on Nextar Entertainment's official Twitter here.

With this event and song, 2BiC hopes to join the list of popular wedding songs following Yurisangja's "To my bride" and Noel's "Proposal".

In related news, 2BiC will release their first mini-album on the 22nd.
