Participants enter the First Love Sharehouse on the first day; check out their first encounter.

The participants write a postcard for their first loves asking them out on a date; it's a first for some and a reunion for others; Han-byeol and Yeon-ju go all the way to Busan to revisit their places of memories.

Participants come back from the dates with their first loves; some still seem to be fond of each other, while some get closure; the radio announces the names of the couples, so they all know who dated who.

Participants go to the designated places for an after-work date; some of them spend some time with their first love, while some spend time with new partners; Hee-ram and Je-seok talk to each other privately for the first time.

True-to-heart stories written anonymously; while they still can't tell who wrote them, the ones who were summoned get to ask anyone out on a date.

Some participants change their minds after a date; they're divided into two groups of four to go to the valley or the Han River; some feelings are hurt as they choose where to go and some misunderstandings are resolved; two new residents join.
