Why Did you Come To My House (2009)

Byeong Hee is having mental problems because of the sudden loss of his wife. Su Jang is wacky, lacks social skills, doesn't have a big dream in life, but dreams of miraculous love. These two disparate strangers are set to soon cross paths. Su Jang was dumped by her first love Park Ji Min (Seung Ri) and has been stalking him for the last ten years. To get a better view of Ji Min's house, she breaks into his neighbour's house owned by Byeong Hee. Once she enters Byeong Hee's house, she finds him attempting to hang himself and saves him. She then ties his hands and legs together and locks him up. Love is about to sprout from the strangest of places.
