I would say this is pretty much your standard gyaru x loner/otaku type rom-com. It is a harem, and there is some annoying commentary here and there about him seeing their panties and whatnot that's a bit too much, but the biggest problem is how it shatters your suspension of disbelief. Like, this supposed Otaku-kun has muscles, is skilled at hair, makeup, nails, fashion, and cooking, has a bajillion hobbies, and overall feels like a poorly done, OP version of Gojou-kun from Sono Bisque Doll wa Koi wo Suru. It's alright I guess, just a bit beggaring belief with the protag.
