Ultimate Shut-in does a different approach to the typical apocalypse survival story by confining its MC indoors, instead of going out to fight monsters and go on an adventure. It is pretty much a mix of tower defense strategy and kingdom building type of manhwa. It's an entertaining manhwa to read, the pacing and growth of the MC is good. The characters and their relationships are solid, as they have their own part of the story that genuinely makes you want to protect. The art is clean and easy to follow. If you're into post apocalypse settings, tactical survival and stories where your kingdom is a crampedapartment complex full of characters you'd look forward to, then this manhwa is definitely worth checking out.
