A fair amount of VN struggle with showing "positive" growth (beyond the MCs magic dick fixing any problem), to the point that it is common for most games to ignore it entirely. Headpats and Handholding however, claims to be (mostly?) focused on that, which is where this earns its below-average rating.
The models are fine (I have seen much better and much worse). The biggest issue on the render side of things is the placement of characters during scenes? If that makes any sense. Having played a handful of games of similar ilk, I felt a weird sense of deja vu, which I can only attribute to the models being in the same (default?) position. This might not be an issue for some but it happened enough that I felt "something". that being said, the backgrounds themselves did not have the same effect, which is a positive.
My main issue with the game, however, is that it still largely fails to be more "wholesome" and, in my opinion, just comes off as "not as sociopathic as 99.99% of MCs," which once again would not be an issue if not for the fact that the "wholesome" aspect is both the titular pull and heavily emphasized in the synopsis. There can absolutely be a good amount of sex in a game while still having wholesome moments (both in sex scenes and in the story), but this lens heavily on the latter while the title, synopsis, and even the developer's signature imply it is the other way.
As a porn game, this is more or less average; it won't be your best game, it won't be your worst game, and you won't want to erase it from your memory or replay it asap. However, if you are a sick degenerate that prefers wholesome stuff, there is enough out there to make this below average even if you were to narrow down the field you compared it against.
