 One shining Sunday, Young-ju is going out dressed up with fancy outfit. She is going to propose to Jun-ho who she has been in love with secretly for long time. However, when she gets the place to meet, she gets a phone call from Jun-ho that he will be late. She is hiding her disappointment because of Jae-gu and Quang-su, a Vietnamese guy, who have been invited with Jun-ho for the date. Young-ju, Jae-gu and Quang-su are spending time together wandering around Itaewon while they are waiting for Jun-ho. Quang-su and Jae-gu are enjoying the day out, whereas Young-ju is becoming bored not wanting to know nor be friend with them.
