Yeah, this manga's problem is definitely the way too long expositions and info dumps.
The characters are fun and the best parts are the loner dude's interactions with others, but so much pages are wasted on panels upon panels of large bubbles expositing on the art of conversation for paragraphs on end. It gets weird when you realize the female and male lead have less actual coversations and interactions, and more the girl just spouting info at him (and us). There are some rare moments, like when she gushes over an old videogame or wants to share meals, where the female lead actually acts like a character and not some info dumper, but these moments are far and between.
The fact that the manga keeps recapping the story so far at the start of each chapter is also grating.
IMO, the author should uses Show Don't Tell more, or at least keep the exposition brief. This isn't a cooking manga.
