Shinhwa's Dongwan reveals the real reason he began to buff up his muscles

Shinhwa's Dongwan gave a slight peak at his muscular figure in his group's latest comeback teaser, but he recently�revealed his motivation to buff up wasn't necessarily for his comeback but to prove his ex-girlfriend wrong.

During filming for�KBS 2TV's 'Happy Together 3', Dongwan revealed, "The reason I built my body was because of my ex-girlfriend. After breaking up with my girlfriend who didn't like my skinny figure at the time, I suddenly began to workout."

Hyesung, who is known to be the most shy about showing his body, shared, "When I first lived in a dorm together with my members, I couldn't understand their pranks, so I used to lock the door and shower." Hyesung also recalled a hilarious story of how he was scolded by Lee Soo Man after showing an extreme dance to get more parts in the group's songs.
