Paripi Koumei (Ya Boy Kongming) manages to take a reasonably interesting premise and turn it into a bland by-the-numbers story. The character writing in particular stands out as dull and uninspiring - Kongming mainly just does some basic "all according to keikaku" stuff, Eiko is textbook waifu bait (and extraordinarily characterless for several volumes), and everyone else is pretty one-note. The story is decently plotted but nothing especially impressive - it tends to bounce around a bit awkwardly sometimes, but it's not a big issue. The artist is not bad but they clearly are not fast enough to handle a weekly serialization. The one thing the story is good at is in making a story that should be a total chore easy enough to read that I was willing to get 7 volumes in, so credit where due I suppose.
Overall a very mediocre 5/10 manga. If you like the premise, I'd say skip this one and just read Shiori Experience instead.
