LEFT PICTURE
The photo was taken during my 2nd single “boku wa kim wo aishiteru” activity. This is a very quiet and yet sad song. During my performance of “Sirius”, my feeling is the same as the picture so passionate. I’m very thankful that I was able to sing this very great song. Moreover, everybody uses the same waiting feelings for “Sirius” to awaits me, let me feel very happy when i perform on stage!CENTRE PICTURE
This was during my meeting with PONY CANYON on the 21/6. As there is still some time left before the recording, this picture was taken. I do not know what will become on the new single, now it is still a secrete!RIGHT PICTURE
This has always been my recording room. Because it’s a personal room, no people is allowed in here so I can enjoy to the utmost during my recording!credit to feiyin@junghoonchina.com & LiliKrist
