You Hee-yeol's Sketchbook
Boohwal Entertainment stated, on January 3, 2014, that Jung Dong-Ha will be parting ways with Boohwal as his contract has expired after their eight-year journey. When inquired about why Jung Dong-Ha decided to leave Boohwal even after becoming the longest running vocalist of Boohwal by You Hee-yeol in the KBS musical program You Hee-yeol's Sketchbook, Dong-Ha humbly answered that, he wanted to discover new side of himself and his singing (which he realized after becoming a contestant of KBS's other musical program "Immortal Songs: Singing the Legend"). He further added that even Boohwal needed some fresh changes to take the band to the next level. So his parting from the band came very naturally as his contract expired.
