Yamashita Tatsuro - Christmas Eve

Just watched Miracle: Debikuro-kun no koi to mahou, and I have to note, that was the first Aiba dorama ever I could enjoy full-heartedly. :) Sweet, cute and romantic. And has a happy end, it's important for me. :)
(And now I have to find out why I found Yamashita Tatsuro's voice familiar and why I know his name, because I don't have an idea of it. x"D)
(Ahaha, I'm fast. x'D So Yamashita Tatsuro is the composter of Garasu no Shounen, that's why I know his name. :) Is it a reminder to go back to KinKi Kids? :D)
