With a title like that, there no real need to talk about the plot, is there? It should be enough to tell that the girl that's front and center to the cover page is our protagonist who starts this doujin as a douchebag guy and ends it as a cute girl.
Why I have that instinct: At first glance, it does check all the boxes in terms of this genre and doesn't really have any noticeable downsides. It does service up the story the title says it will, and does it pretty competently. And it is definitely very arousing if you like the setup and the genre.
The things holding it back for me is... it's too simple for my tastes. The story delivers and has all the elements the tags have, but it just doesn't go beyond that. It delivers, but that's kinda all it does. There isn't anything surprising or super interesting on how it gives the content, it just does it. Characters don't really go beyond the tropes, the story doesn't really evolve or go in other directions (except arguably for the end, which was honestly nice to see), and the writing doesn't really feel the need to go a step beyond. It truly is exactly what it says it will be.
And in terms of too simple, the art style isn't exactly my tastes either. It's not bad at all, good even, but it's noticeably economical (read: I can tell some corners were cut) and not especially detailed. Everything is a little too clean and smooth for my liking, even the fluids, and the poses the character makes feel pretty... to the point too. Again, it's not bad at all, and I certainly don't need/want every hentai to look the same. I do think that we would be worse off if this art style didn't exist, and artistic variety is nice to see anywhere and appreciated. Just, you know, look at the preview pages before buying and decide for yourself if you want to see more of this art, because it will not surprise you beyond those preview pages.
I have some familiarity with this artist from... elsewhere, and I do think they've done better, but it is nice to give a little support to them for this work. And really, there's only so much I can bitch about for a doujin that I did orgasm to and is still aroused by. You do get exactly what it says, after all. That's appealing in its own way for sure.
