Jae-young Kwak

A young man sees a drunk, cute woman standing too close to the tracks at a metro station in Seoul and pulls her back. She ends up getting him into trouble repeatedly after that, starting on the train.

Shy Ji-hae's friend is having problems expressing her feelings to the boy she loves, so she asks Ji-hae to write e-mails to him in her name. As the boy falls in love with her letters, Ji-hae discovers the story of her mother's romance which is remarkably similar to her own circumstances.
