A very good plot which is cute, fun, romantic and mysterious. Great chemistry between the two leads. Female lead in particular was perfect. From her name (Na Bong Sun) to her acting. Park Bo Young really made the role hers. Pace was good but a rushed ending in my opinion. I was disappointed why Seon Woo ( who admitted he fell in love with the ghost ) did not bother to look at her picture(Shin Sun Ae) to see her actual face when so much happened between them and Seon Woo told her ( Shin Sun Ae) to be responsible for him since he had chosen her. It would be really nice and realistic if there was a scene of Seon Woo holding Shin Sun Ae's picture in his hands and shedding a tear or two ! Would had wanted more touching moments and scenes between Seon Woo and Shin Sun Ae when she bid him goodbye. Afterall, they did loved each other once. This is what i find lacking in this drama. Otherwise it would had scored a perfect 10/10 !
