Story:-
Tae-suk (Jae Hee), lurks around the neighborhood on his motorcycle, looking for unoccupied residences where he can stay. Placing flyers in keyholes of the doors, Tae-suk gets to know that the owners aren't in, when the leaflet isn't removed. Then he breaks in and spends some of his days in the house, but never steals or breaks anything. Instead, he guards the house and goes to the lengths of even doing their laundry.
Tae-suk's unique lifestyle brings him to a woman who would change his destiny forever as the nomad sneaks into a mansion, owned by married Sun-hwa (Lee Seung-Yeon). Oblivious to the fact that Sun-hwa is present inside, Tae-suk sneaks around. As she observes him, monitoring his every move, the woman realizes that the Tae-suk wouldn't harm her. She confronts him in the night, but he slips off, after a phone call from her abusive husband interrupts them.
Haunted by her imploring, depressed eyes, Tae-suk returns to the house, but Sun-Hwa is unaware of his presence this time. Tae-suk prepares her clothes when she gets into the bath and also puts on some music. Sun-Hwa senses that he has returned. Unfortunately, the peace within the home is destroyed the moment her husband returns, to sexually force himself upon her. Angered, Tae-suk picks a 3 iron and knocks out the husband with golf balls. Tae-suk and Sun-Hwa make an escape and Tae-suk introduces his new friend to his nomadic life. As they grow close, Sun-Hwa finds peace and love in Tae-Suk, but their new found joy isn't meant to be, as things go very wrong when the couple enter a home and find an old man dead.
