The writer of the story straight up calls out the romance in the most recent chapter where they go to the movies. He has the main male character think that the romance is taking too long in the movie but that it's kind of normal for a romance stories. Which if that isn't a subtle call to it I don't know what isRomance should not be expected. There are end shots every now and then but its evident any real romance will take 100+ chapters to develop. This is a slice of life story with romance as a side piece.
When you're done virtue signalling with your flaccid steel, you could try just reading the series instead of making nonsense comparisons that have no relevance to...anythingI remember dropping this a while ago because of Ch.3 and forgot about it. Surprised that there's already 37 Chapters. Well, might as well reread it again.
Let's see if there are any other NTR Bait / Rage Bait plots in the future, because Ch.3 was done intentionally to provoke the reader into something or to make it controversial.
Then again, this could be another self-insert by the author cucking the MC situation, like Rent-a-Girlfriend.
