Shoko Nakagawa: There’s a bit of a story behind when I first heard about Sorairo Days. I was really happy because I always wanted to sing an anime song, but when I went into the recording session I thought somebody else was going to sing it too and that I wasn’t the only candidate for this song. I had mixed feelings, and was kind of anxious about it. I did my best because I really wanted it. After the recording I heard the management say that it was going to be me, and I was speechless. Before the first episode came out I kept wondering if it had really happened. When episode one came out, I went to Akihabara and I actually saw this man buying my CD. I still remember that I wanted to shake hands with him, but I thought I might look like a weirdo or something. I was really happy and it finally made me realize that it had happened.
