A project created to help Young K make up for the childhood memories he missed out on. Because he moved frequently throughout his school years (spending 5th grade in Vancouver, 6th grade in Ilsan, 7th grade in Toronto, transferring to another school in 8th grade, attending high school in Toronto for 9th and 10th grade, and then returning to Korea), he says he doesn't have many childhood memories with friends. In this series, he experiences the things he never got to do back then together with guests.
