Idol Lee Jae Jun, model/actor Lee Ji Han, actor Seo Byuk Joon, and rookie model Ahn Hyo Sang start a vlog channel about their trip to Okinawa, Japan for a photoshoot. The four meet for the first time (aside from JaeJun and Byuk Joon, who are longtime friends) when they learn they will be sharing a home during the trip.

The vlogs show how their individual friendships develop by the end of their stay and after coming back to Seoul, some even beyond just platonic.
