Ah yes, the good old story of an otaku who has no interest in 3D girls yet is surrounded by beautiful, sexy girls who want a piece of him.
Does this anime do anything different from its predecessors? Barely. Almost every trope you expect in this type of anime is present.
An MC with an overly exaggerated otaku personality where he poses every single minute, saying, "I DON'T NEED REAL GIRLS, ANIME GIRLS ARE ALL I NEED." But here's the catch—he actually has a very good reason to be this way. Being left alone by your mother at 8 is pretty bad, right? Even at school, everyone looks at him like he's a trash bag, so it's pretty understandable for him to act like that. Is his posing every minute and yelling "I DON'T NEED REAL GIRLS" at the top of his lungs cringy? Surely this level of cringe won't bother you. If you can handle something like Rent-a-Girlfriend, then you can certainly handle this.
The anime later introduces heroines that seem even crazier than the MC. One of the heroines is into erotic things to a level that even the MC can't match, and another heroine is a popular and cute model who looks at a chronic weeb who keeps saying how much he loves anime girls and thinks to herself, "Yeah, I love that guy."
Going in, I thought the MC would be a dense guy who keeps saying, "I don't care about 3D girls" until the very last episode. But nope, in the first episode, his entire motto and way of life shatter after he lays his eyes upon a girl doing sexy cosplay. Turns out, he still likes real girls after all, but he keeps hiding and denying it by saying, "Oh no, I don't like real girls, I won't see you with dirty eyes" (he obviously does) and "Oh no no no, I don't fall in love with 3D girls, I FALL IN LOVE WITH 2.5D girls" (there's no such thing as that).
As far as the story goes, this is pretty much the main plot: an otaku slowly realizing that he loves real girls just as much as he loves his anime girls. Sure, the anime will have its serious moments discussing his upbringing and why he shows no interest toward real girls, but that's about it. Nothing too serious or overly dramatic, besides people come to see this anime for sexy anime girls, nothing else. Which leads us to the fanservice.
The fanservice in this anime is mostly subtle and teasing rather than full-blown nudity. You won't see bare nipples or sex scenes. Rather than relying on nudity alone, they cater to using lewd moments, eargasm, and the sexy design of the heroines' outfits. And trust me, it works because the creator made the heroines' designs so FCKING HOT. They are cooking with it. Sometimes this subtle lewdness is much hotter than full-blown nudity, and this anime proves it even further.
Overall, if you are into ecchi with a light story, give this one a try.
