Right. I didn't know (or remember, maybe), that Nagatoro had a pre-serialization version.
Hm... Not sure you explained it, tho. Okay, so in Chapter 3 she admits she's been too hard on him. But why? That's the main thing. HOW did the author bring the character from fucking psycho to cute girl? What's the reason she gives for being a fucking abusive sadist? What's her excuse?
Cause from what you wrote up there, what I see is "Dude, I was so asshole-ish to you, why didn't you get mad? Anyway, sorry, lol. Wanna be friends?". And that is so fucking absurd that it brings the rating of the manga down, as I said. I could see why people consider it a Romcom (AFTER chapter 3), but not how anyone would put it in a Top5: the character makes no sense.
See what I mean?
Hm... Since I sometimes have trouble online with my way of writing. I'm not attacking you, or trying to be rude or anything. Just asking for information, or whether I didn't understand something. It's possible that you just didn't mention HOW the character evolved in Chapter 3, and what her reasons are. Or it's possible that it's literally what you wrote, no reason whatsoever, just the author being mediocre.
That's the nuance I wanna clarify.
