You would think with a 30 chapter story, there wouldn't be a lot of points it meanders around. You would be mistaken. Both Sachi and Ruka's relationship is put on the back burner for development for a lot of yuri subplot until the last 8 chapters. It was annoying just how little Sachi and Ruka were even on a page together between their introduction and the last few chapters. The convoluted part comes from the "revelation" about who or what Ruka even is. I'll leave that up for you to read to know what i mean.

Ok so I like this series like the first few chapters and then around chapter 5-7 it got worst, i dont think this is too much of a spoilers but I'll censored it anyway,

when they introduce the other girl with Fate Factor it went fckin down hill for me, this is becoming ntr with extra steps it's basically a yuri manga now for god sake the MC keep being cucked by the other girl is fckin bs and the female mc just keep doing it with the other girl holy shit, also the guy is a beta holy he never went for the initiate or even do anything, even tho the female mc keep advancing on him. Just let this be a Yuri manga by the amount of time the female mc keep doing stuff with the other girl, holy shit this Author. Also harem my ass there's no way this is a harem.
