Mother and a Guest

Ok-hui (Jeon Young-seon) lives with her grandmother (Han Eun-jin), her mother (Choi Eun-hee), and the maid (Do Kum-bong). People refer to their house as the "Widow House" because all three adult women who live there are widows. One day, a teacher named Mr. Han (Kim Jin-kyu), who is a friend of Ok-hui's uncle, moves into the house as a lodger. Never having known her late father, six-year-old Ok-hui takes to Mr. Han as if he were her real father. Ok-hui's mother and Mr. Han develop feelings for each other unbeknownst to prying eyes, and Ok-hui shuttles back and forth between them as their messenger of love. Mr. Han sends Ok-hui's mother a letter confessing his love for her, but she rejects him out of concern for her mother-in-law and Ok-hui, and Mr. Han departs for Seoul.
