The author skips over important things like fleshing out the two dimensional characters and then we get super condensed plot and deus ex machina in the form of Ayato?
MC and Nao's love story is shit. Author makes it seem like they have this deep connection, when in fact, shes hoeing on MC's best friend at the start, and they only got together because she has no one else to ho but MC. Yandere girl had a better story and deeper connection to MC, loving him ever since they were kids.
Ni66a you've been in love with him for about 3-4 chapters. Stop acting like yall soulmates or some shit. Yandere girl was the better girl, and so far, the best girl.
