Hmm.. kinda bummed that I'm just coming across this now since there hasn't been a chapter translated in ~2 years.
At the time of writing this comment, it appears that the raws are up to Ch. 18.
Hoping that someone picks this up Soon™.. interesting concept. Revenge stories can be fun, but they usually just quickly resolve it or jump into bloody murder.
Having someone this twisted, but not after blood, but to get their revenge by living happily and being loved by their people to then drag his revenge target's name through the mud is quite interesting.
Looking forward to how this develops since it's not a revenge that can just be plopped out to just happen, force the story down silly paths, or quickly resolve and then have new things come up.. lookin' at you certain manga that I can't remember but that has the MC who even went to get revenge in Hell and whatnot..
