He wrote:

"May 6, 2005 was when my first solo album released, and the next day, I had my showcase... It's been 10 years already. I still can't forget every throb and tremble I felt at that time. These days, I've been spending my nights watching past videos moreso than before... I would be laughing and crying alone like a crazy person... A lot has happened in the past 10 years. Being with you guys all this time, crying and laughing together, is very special and has become a great strength for me. Thank you, a lot more than what I can express with words. Thank you for staying by singer Shin Hye Sung... And I love you..." 

Live Works Company also asked fans to continue and support Hyesung, so that he can one day become a memorable singer who resonates in peoples hearts. 

Meanwhile, he'll be joining his members for the Shinhwa Asia tour this September, starting from Shanghai.
