Unbeknownst to him, his YouTube love song was posted on the homepage of YouTube. He found out when a friend told him. He soon received requests for new songs, a live performance, and an album. He wanted to release his songs in an album, but as he was already technically a signed songwriter/producer at that time: He had to go through legal procedures and accept a variety of contractual conditions. Thus, he left Warner and stayed unsigned to carry on with his own album release. Choi released his first album in 2008. Entitled "Only You", it contained mainly love songs, notably "Love", "Won't Even Start", "Something To Believe," and "Only You". In 2009, he released a Korean special edition of the album, containing three bonus tracks. "Won't Even Start" became his hit single, and he released a music video for it, collaborating with Wong Fu Productions in producing his first official music video.
