'10 Star' magazine released photos and interview of Ha Sung Woon. 

After completing the springy pictorial with the concept of 'romantic guy,' Ha Sung Woon talked about his solo debut with "Bird," goals, fans, and more. 

To the question on his favorite physical feature, Ha Sung Woon named his lips, and said, "To be honest, I didn't like my lips but my fans often told me I have pretty lips so I gained confidence. My dad and grandma both have thick lips so I knew mine were thick too."

More of Ha Sung Woon's interview can be found in the April issue of '10 Star.'
