Long story short, MC#1 came from a group who rebels against a God-figure. MC#2 was a spy sent from the side of the Holy (God-figure), but MC#1 never knew. They were childhood friends and grew up to lovers. During the finale of the war, the God-figure revealed MC#2's origins, causing MC#1 to think of it as a betrayal. Further more, MC#1 and MC#2 was raised by the same mother-figure, so when God-figure threatens to attack MC#2, mother-figure came in the way and died to protect MC#2, furthering MC#1's crash out.

On the other side of the story, MC#3 and #4 are also another group of childhood friends-now-like-each-other. On this side of the story, it works more like the apocalypse came (you can take it as MC#1 and #2's world invading #3 and #4's, which are basically the earth.) It's taking a similar world-building to ORV. Through the story, MC#3 and MC#4 met MC#1 (long after the war, where MC#1 gets banished far away, which is to the invaded earth). The three of them tries to figure out a way to "get out" (it's hopeless to try to stop the apocalypse) of the earth now filled with monsters and alike. Throughout this journey, MC#1, #3, and #4 grew a bond and the three became lovers.

Later on in the story, MC#4 fought the other two and sacrificed herself to let MC#1 and MC#3 pass on (something like the Demon King Scenario). Now there are only MC#1 and MC#3 left, and after the sacrifice, they kind of got separated, sent through other places. My story is very incomplete and filled with holes so I can't put names yet to the characters and places LOL. MC#1 and MC#3 had only met again before the finale of the story, where MC#3 finds out MC#1 figured out a way to end the whole apocalypse by replacing the God-figure with himself. But that means MC#1 will forever be stuck within the apocalypse, and MC#3, alongside the group of rebellions they've made, disagreed with.

Unknowingly, after the previous war, MC#2, who had always hated being the God-figure's pawn, had secretly followed up MC#1's journey, secretly helping him continue and go against obstacles in his journey. Despite still loving MC#1, he decides to let him go and let MC#1 grew his bond with the other two MCs. He had ended up sacrificing himself when MC#1 (along the other MCs) didn't succeed in escaping the apocalypse. AKA, the bad ending. His sacrifice helped with "restarting" and creating a new timeline to help the rest of the MCs achieve a world beyond the apocalypse. His sacrifice was only found out at the finale of the story, nearing the epilogue.
