This drama is such a torture .... why the hell you fall in love with your dead girl friend... younger sister... there should have put more chemistry between L (Kim Myung Soo) and Krystal... Rain should have just help her out like her sister....plus Rain acting was kind of childish around Krystal ....and he look old too. L and Krystal was looking good together ... the only good thing of this drama is the song of Alex chu - I Want To Love You 사랑해줄래 ... love this song.....
