Kim Hyung-min

Gwang-ho is bored except for the time he's taking off his girlfriend's underwear. He visits his Seoul home at the news that his grandfather is dying. Amidst the awkwardness, he remembers something. Ji-yoon is his cousin who has grown up to be a young lady. Gwang-ho is attracted to the fully grown woman and the same is said for Ji-yoon.

Two brothers, Kwang-sik and Kwang-tae, have very different attitudes toward women. Kwang-sik is extremely shy and can't say a word to a woman. But Kwang-tae is a playboy who just sleeps around. One day, Kwang-sik meets Yoon-kyung for the first time in seven years and he tries to confess his feelings to her, in his own way. Similarly, Kwang-tae meets Kyung-jae during a marathon and he tries his own ways on her. At first Kwang-sik still finds it very difficult to even talk to Yoon-Kyung and Kwang-tae thinks of Kyung-Jae as yet another temporary conquest, but in each case something changes in the brothers. Will they be able to love this time?
