Renai Shashin by Ai Otsuka
I saw a video of WaT with a link to this trailer of Tada, Kimi wo Aishiteru. It stars Aoi Miyazaki(NANA) and Hiroshi Tamaki(Water boys & Nodame Cantabile). I watched it since it had Chiaki in it and Garten made in Memento. I found the song in the trailer very good and I sort of found the voice familiar. It turns out it was sung by Ai Otsuka. The song's name is Renai Shashin. In a previous post I said that Ai Otsuka did make Sakuranbo which is a super bubblegumpop song that is very different from the feeling of Renai Shashin. Told you she could be senti XD.
