The next day, Yu Jin and Joon Sang were disciplined by the teacher for playing truant. The teacher asked whether it was Joon Sang who took Yu Jin out. Yu Jin defended that she has gone out by her freewill. Both of them were ordered to clear the fallen leaves in the yard for one month as punishment.

Joon Sang went to see Zhen Yu in his office. The latter talked about his son Sang Hyuk, and Joon Sang is disappointed that he did not remember he has another son...

In the broadcast room, Joon Sang brought a LP with the track "the first time". Yu Jin told him that it was the first time she skipped class, the first time on a bicycle...
