This game certainly has quite a lot of promise, but it's severely lacking in direction. It's crazy for a game to be almost 2 years old and not actually have a true focus on any LIs. Everytime a LI starts to get some shine she's promptly shuffled off to the shadow realm, then the MC decides to leave for an entire month about half a week after he decides that he can actually talk to his peers again, which then magically transforms into 2 months, at some point. The Mom baiting is also more than a little obnoxious. You clearly spent a lot of time and effort to get the Mom to look as good as she does, you even put her right in the middle of the banner, which is typically where the main LI of a game goes, but then you say she's not a LI, despite including incest with the sister (or at least planning it). It's utterly schizophrenic game design.
Also, the MC seems to be the absolute king of rebounds and sloppy seconds.
