Jean is the MC and the devil twin and The other one (i forgot his name, but his an angel... And died :c).
Jean made the zombies bc he hates live people cuz...you know, NECRO BOI, and made experiments on himself to live for a long time (he's like 63 years old)
Also, the zombie had a STRONG Stockolhm Syndrome with Jean

I read the raws with Google translate and didn't get the whole story.
But from what I gathered there is a plot with an evil twin of the young guy, but I could never figure out who was the evil one... They worked in a lab and possibly started the zombie thing.
The Main characters also get an additional - a little zombie girl who was abandoned by her parents.
The ending seems to be happy but a second season was announced and then postponed indefinitely - such a shame. There was even a cliffhanger with a hatch in the garden and Boone knew who was in there.
