On this day, Sung Duk Sun rode a full bus to go to school. As there were a ton of people, she was barely able to stand in the midst of all the male students. Whenver the bus stopped out of emergency, the male students started to call cat calls. As Sung Duk Sun was uncomfortable, Jung Hwan looked at him little by little just to check her out.

As the bus came to a sudden stop once again, Sung Duk Sun ended up falling. Then again, as she was falling, she pulled on Jung Hwan's clothes. All the buttons on Jung Hwan's clothes fell off which led to another funny situation.

With this, it will be interesting to see how this series will continue the trend of the Reply series and attract a viewership spanning decades.
