Hyung-man is in his fifties and has regrettably never dated. After having lost all his money to a close friend, Hyung-man spends his monotonous and frustrating life in his photo studio.
One day, Hyung-man decides to pay his fraudulent friend, Ki-hyuk, a visit, after having heard that he is dying of cancer. Ki-hyuk requests that Hyung-man look after his daughter, Nam-eun, once in a while after he dies. After Ki-yuk passes away, Hyung-man decides to visit his friend's daughter, who is surprisingly a full-grown lady. Noticing that Nam-eun is more distressed over the death of her pet cat than her father's, Hyung-man decides to look after her once in a while. Nam-eun too finds her father's silly and unmarried friend quite interesting. Using Hyung-man's dirty laundry as an excuse, Nam-eun frequently visits Hyung-man, gradually expressing her feelings for him. Although awkward and surprised at first, Hyung-man too is curious about his feelings for his friend's daughter.
Soon, Hyung-man who was once simply Nam-eun's father's friend becomes her man and they begin a series of unusual dates.
