I like how she's just carrying around a bag labelled GAY. Like, I've got to get this precious gay to the hospital, this guy needs 150ccs of gay immediately.
For my own happy ending I'm just going to say that the girl that left came back a little bit later Also I think eventually Dynasty should get a Polygamy tag. While it wouldn't really work for this manga it could work for Two and Two.
I can only hope for a happy ending from this manga. That guy did say that it was for his research so maybe there is a chance that they are working on a cure that can save Makoto and the other Zombies
Would this technically be age gap? Seeing as out MC is in High School and the Love Interest is in College? Or was there not enough between them to achieve that tag?
