Neighbours Ho-jung and Kyo-in as youths have developed a quarrelsome relationship.
As a youth Ho-jung made several blind dates, namely Jae-young, Hyun-min, Jin-sung and Jeong Hoon.
Ho-jung protests that no woman will accept it with that kind of history.
Their friends, Soo-ji and Ho-jae, met stiff opposition from their parents since their youth when they developed relations.
When Ho-jae was about to be enrolled into the army, Soo-ji ran away from home for a day, even forgetting to put on her shoes.
Both of them later happened to be on the same subway platform, Kyo-in tried to give chase when Ho-jung got on the train but the doors closed as he rushed towards it.
Kyo-in got on the next train and sat on the stairs that he visited frequently with Ho-jung.
When Ho-jae returned home, he was rather shocked upon seeing Soo-ji's unusual behaviour. Hearing that, Soo-ji's mood changed for the worse, and asked Ho-jae to make his point clear.
However, his attitude briefly changed for the better when he realised that Soo-ji wanted to spend a romantic night with him, saying, "Why didn't you say earlier? Ho-jae's attempt made Soo-ji even angrier, and she pushed him away when he tried to approach her.That night, he brought her to a karaoke, and sang a song. Finally, Ho-jae and Soo-ji got married in a mini-celebration with the approval of their parents.Soo-ji and Ho-jae bumped into each other when they did the traditional Korean bow, which created a comical atmosphere.The friends were a little surprised when Kyo-in showed up late.One night, some time later, while returning home from work, Kyo-in and Ho-jung happened to pass the same shop window and both thought of their past memories.At this time, Ho-jae proposed to Soo-ji, but they met with stiff opposition from their parents.
