It's good if you don't look too deep into the plot. I don't know about the 'realist' part about the manga. Everything the MC needs seems to be conveniently aquired. The set-ups for the twists in the plot are obvious and predictable.
The romance only started brewing in the late chapters, then it ended. The manga ended abruptly making it feel like a sex-ed. This manga was cancelled wasn't it.
I just discovered that this series has a manga yesterday. I don't know why but I find the manga less enjoyable. Maybe because the web novel delivers the story more slowly to the reader. The story's comedic punchlines felt more natural and less anime-ish.
For the manga-only readers, in case...
I just realized that this has an anime ehile scrolling the comment section. I don't know if I should watch it or not since I just binge the whole manga in three days. Is it well-animated?
The story is mediocre and the art style doesn't fit the kind of manga it is. The art style looks like something that mangakas usually use to draw 4-koma gag mangas
