Edeus + Junghwa = OTP??
Edeus = has a crush on neighbourhood konbini cashier girl; turns out!!! he has a handsome rival (aka Junghwa, the popular host of number one host bar The Lotus). Ends up hating Junghwa's guts.
Junghwa = honestly doesn't care about dating Seonyi bc cousin. But then he notices one of the Hero party's helpers watching over Seonyi and he just has his sweet little revenge by doing things that appear to be slightly romantic.
Eventually they actually come across one another and mexican stand off 'what are you to Seonyi' 'what's it to you' etc.
Duke it out all the time
Junghwa gets his identity revealed along the way but Edeus pretends to be an idiot bc all demons are meant to be reported and culled on sight.
Fall in love along the way idek how yet but they will!!!
