Dreams and Reality

Sunghoon and Heeseung have been dating for a while, except they have never met. Not while awake, at least. Jungwon and Sunoo are convinced Heeseung is not real and Sunghoon is just delusional, so they try to set him up on dates. Sunghoon always refuses, but what happens when Jungwon asks for for a favour going on a double date with his future potential boyfriend and a friend of his?
