There's also a devoted fan of Han Se Joo who mysteriously turns into an anti-fan 'Jeon Seol' or 'Legend' (Im Soo Jung), and not to mention an antique typewriter laying around.�

The first teaser opens with Yoo Ah In saying "There are two things I don't really need in my life: a ghostwriter and a girl...They have arrived."�Set in an eerie land of mystery and romantic comedy, the scenario seems to entice viewers with its intricate plot.�
