User blog:Gundam 00 Raiser/A question

Hello there, as you can see there, my user name is Gundam 00 Raiser, I'm also called Enclair among my friends.

I recently started watching the anime, I finished both seasons, and it's a great anime for me. With that in mind, I got a question. I noticed that there is a really beautiful OST in several episodes as BGM. Like episode 8 of season 2, and several more episode. It's this piano background song, and I've been wondering about what's the song name.

So, any one have an idea of what's the name of the song? I'll be really greatful if somebody tell me. Thanks before hand :)
