Keeping a Diary in Genshin Impact, My Daughter Comes Knocking!

This author really loves soul-swapping; do you dislike your own body that much?

None of the daughters have the male protagonist's surname, and then they try to force a connection with him.

So many chapters, and I haven't seen any exciting moments. Instead, I find the protagonist a bit sleazy.

It's clear that the protagonist's intelligence has been lowered. Even a normal person wouldn't believe that they suddenly have a daughter from the future, but they would definitely have doubts and then try to test and deduce further. But the protagonist doesn't even have the thought of verifying anything. It's really a case of lowering intelligence. Not to mention that the protagonist is a transmigrator from the new era. He has even played Genshin Impact. How could he not know Ishtar?

I don't think the male lead seems like a time traveler at all; he's too bland and doesn't seem like someone who'd cause trouble.

The author's values ​​are questionable. Mio nearly killed Kuki Shinobu and so many soldiers by blowing up the prison, and the protagonist didn't seem to care at all. He also casually let it go when the engagement site was bombed, killing so many civilians. How many soldiers did Mio and Kujo Sara kill in their fight? And the protagonist still protected Mio?

I have a crazy daughter who infuriates me. If I can't raise her well, I shouldn't have had her.

The standard features of a protagonist in an ancient fantasy novel: unparalleled martial arts skills, the ability to bring the dead back to life, and mouthwatering culinary skills. Instead of reading cookbooks, why not look for books on dual cultivation (a concept in traditional Chinese medicine), which repeatedly emphasize the female protagonists' inability to withstand the protagonist's strength?

Under what circumstances can children not take their father's surname?

I once read a novel of a very similar type, where the daughter comes looking for her mother. But they went even further. The daughter, mother, and a whole bunch of others ganged up on the protagonist, treating him like a lackey. The poor protagonist was led around like a dog.
