Been a good chaotic week so I don't remember everything beat for beat, but err uh...
Basically, they manage to get out of the campus grounds and go towards the military base. However, as they're getting there, they're shot at by the military, believing they are zombies. Youngwon gets shot in the stomach. The gang skedaddles for cover, and eventually a squad of military patrol the area, and there Hohyun grabs one as hostage and tells them they aren't zombies and blah blah blah (think you get it). Then the next chapter is just Hohyun waking up in the hospital and explaining how they cured the virus or something, and he later goes visit Youngwon's hospital room. Everyone lived, the end!
Meanwhile in the novel it shows an alternative bad end, where Youngwon and Hohyun both die from the military, and instead of just Youngwon remembering the cycle, Hohyun does too now! WOO!!! However, both of them have no hope for the future, so they just hole themselves up in a building and just go at it like animals...

There's only a few chapters left till the end... I read the raws (won't spoil the ending) and there's no side stories so far which kinda suck since the ending seemed really rushed AND ALSO THEY GOT COCKBLOCKED LIKE 3 DIFFERENT TIMES... Like please... I need to see them do it one last time at least...
