The first volume is pretty good but it gets a bit repetitive and is way too slow. The story is dark and deep but goes at a snails pace. Written like a diary from day 1, day 2 etc. The story moves so slowly that by volume 5 they are only up to day 62. The army takes 10 days to get there and that is already gone through a whole volume and 10 days haven't gone by. The main plot is home decorating cooking and girls either complaining at the MC or giving him dirty looks. The MC doesn't remember anybody's name which is funny because everyone gets upset about that. Lots of dangerous and amazing things happen but the way the MC explains everything is really dull. Way to slow and repetitive. The author really needs to skip days and make the actual fights more interesting. You should definitely read the first volume but you don't really need to read the rest.
