Apink mini album Secret Garden was released in 2013.
This album includes three songs. The title song “NONONO” was produced by Shinsadong Tiger. The song “NONONO” has a bright-sounding melody And lyrics about encouragement. until it was named as the "healing song". I like to listen to this song when I feel tired of something and when i feel bad. I get strength from this song and make me courage to move on. “Lovely day” was produced by Golden Doohyun. This song talks about a girl who falls in love with a man. I like this song because it has a lovely melody. I enjoy listening to it while working. The last song on the album is " Secret Garden ". This song has a meaning about a woman who didn’t dare open my heart to love. Until he met a man who can open the door of her heart and wanted him to come visit her Secret Garden. I like this song because it has warm-sounding melody and I always listen before go to bed. There is nothing that I don't like on this album.
