My favorite song is "Hello" because it's so catchy and fun! I also really love Onew's voice and I hear it a lot in this one! My favorite M/V is "Lucifer" because I absolutely love the dance in it and all the guys look hot in it especially Taemin.
Here are some cute gifs of Taemin from the Lucifer M/V! Geez he's so sexy with longer hair and a great dancer.
