..I just wanted to read a cute, romantic manga.. and this shit came up, vomiting my eyes out.

It's pseudo incest.
This site there is a lot porn. I don't know how you expect a title with My Daughter in a porn to be wholesome. He is her surrogate dad. You know from the title AND the description AND the reviews AND ppl who posts summaries of what the content will entail, and yet you still consume it. Idk how much you've read, but if you knew these things still going in idk what to tell ya. Most porns are like this. That's why I don't read them half the time.

I didn't know it came up in the tags..and I've no idea why some would tag this as cute. And even if they did, you can see from the cover it's porn.
Also, you must have some experiences with porn there's all kind of questionable themes.
This particular one didn't seem to have a summary. But a lot of ppl have left comments on how gross they think this content is.
Everyone was taking about how it was on the featured page. Didn't know your source came from a search tag l.
But either way, now you know. And if you hadn't known before about questionable themes in porn, now you do.

But even if it's not porn, there are stories involving incest (like step brothers) (I read mostly BLs) that wasn't pornographic in nature. I didn't ever finish the story so I don't know how physically close they got, but they were half siblings. In that instance no one forced themselves onto each other physically, but the younger sibling had a strong attachment to his older brother.

From your OG post though, you said the author likes children, no they're not adult and minor. But big age gap. And if you were searching for more healthy/wholesome content, then I'm sorry you ran across this. Lol. But from the cover pages I'm sure you can more than guess it's not what you would consider "wholesome".

I only commented because it said “my daughter,” thinking it was actually his daughter, but I guess it wasn’t. And no, I didn’t think this manga would be wholesome because of the title and the image of it. All I did was search up ‘cute' in the tags, and this is what I found, so I came into the comment section and stated my opinion on the title. I didn’t know the female character was an adult; I thought she was a minor, so I commented as well that the author likes children, because I assumed that the female character was a minor. The point is I was making a harmless joke.
I stopped reading Immediately when the child came up
