I think this was the first album where I felt most connected to Ayu, all while I was fan when albums were released. (Like, I wasn't a fan when her first few albums came out; I didn't start following her until about 2005/2006.)
Secret holds a special place in my heart. It isn't my favorite album, but not my least favorite either, just...special.
I also remember all the promotions she did for this.
Ah, good times, good times...
