Krystal doesnt express well, but she loves him. So she tell him what she feels in the letter. ForewordI remember every detail of how you said your love to me, I know so much about your favorite singer during high school because i went to internet to know everything you like. I even change my hair color not because i am a fashion addict but because you said on your homepage that your favorite female singer change her hair color and you love it. I do silly things but you think i dont.
