It’s Takahashi Ryuuki.
At this time, in order to focus on my physical health and recovery, I, Takahashi Ryuuki, am graduating from the acting group D-BOYS, as well as the entertainment world.
I’m sure many of you are surprised by this sudden announcement.
I’m really sorry.
Since last month, I’ve been thinking that something’s wrong with me, and when I went to the hospital, I was told that a more detailed examination was necessary.
As a result, I found out that I would need a long treatment and recovery period, and after talking with my family and staff, decided that my physical health is most important, and arrived at this decision.
Thank you very very much to all of my fans, staff, and officials who have supported me up until now.
And to all of the staff and officials I’ve caused trouble for due to my bad health, I apologize.
For now, I’m going to focus on treatment, but when I recover, I’d like to take another step forward.
Thank you very much for everything.
Well all we can do is supporting him although he's not a D-B member anymore *sigh*
