Dreadful is the only way to describe this absolute pile of crap. The plot is pretty much nonexistent, and I'm sure you can guess how it goes in this Pretend Lover #5961 series, and don't you worry, the story doesn't try in one way to set itself apart from those, so if you really do like those this is the series for you. Past that, the plot has been absolutely nonexistent, which normally is not a problem for many series, they can pull off episodic chapters easily, this is not one of them. The episodes come out to such a generic, uninspired, overdone way they are really forgettable to the point where I can't even remember a lot of the time if I've already read the chapter or not, like a disk reader they're completely wiped from memory after you finish the chapter. And Jesus Christ, the retconning. It's everywhere. Like after every "arc" there's a shocking revelation in the "plot" that girl X was actually not coincidentally placed to fall on MC's penis! There's only so many times you can use the "When in doubt, add more girls card" and this series has done that trick about 7 times now.
The girls themselves aren't much better. As you can guess from the synopsis, the generic loser MC suddenly finds himself overflowing with vaginal fluid, even younger sisters start wanting him, all for one chapters worth of effort mind you. This is how it works out for every girl, MC does a nice act, you get about 5 panels of embarrassment, and then a corny line at the end of the chapter to wrap up the obvious feelings of "love" that sprout if you're too stupid to catch it.
The only thing not vomit inducing about this series is the art, which is quite nice, but I don't know about you, art is not the make or break factor in a series, and I firmly believe he could have drawn the most amazing scenes and it will still not save this.
Frankly, don't pick this up. After 97 chapters I'm certain to drop it soon, as I can't bother to waste my time on it anymore. People might say to try it for the cute girls or the funny panels/expressions, but that is exactly all there is to this manga and if people recommend this to you they are TROLLING.
