I can think of some ways it's gonna end, one, they both smh die like it could be that bada dies and he doesn't get "reborn" and because of it Doha kills himself, unable to play the game without his lover, two, Bada dies and Doha gets back to real world only to find Bada, three, Doha dies and Bada finds out he's actually a player, and gets back to real world or sum, four, they are lovers in real world but because of the contant playing they both forgot and their memories are mixed up and they find out and exit the game together. There are actually so many ways it could end and I hope it will be a good ending + I don't believe Bada doesn't exist irl like something is fishy here
