[TRANS - More Than Company's comments in Single Bells chocolate post] Yeah, it's really full-hearted. The handwriting was selected after he tried to write over and over again. It seemed that he elaborated on it so much because it's the message to his own fans. I guess the chocolate will be a nice gift for you guys. [...] I had heard that the gifts in celebration of the 10th anniversary of his debut would be only for 1,000 fans on a first come, first served basis. He really ordered the exact 1,000. [...] The handwriting is what Jaejoong himself sent to us through Cafe J Holic. Of course, also the photo of Hiro is what he sent.
(t/n: Sorry for the incoherent flow due to omission of advertising words for the company. LOL!)
