Let me begin by saying that this is not Nevertheless, it's completely different from the source material and I mean the webtoon not the Korean adaptation,
So if you want to watch it because you loved the webtoon/kdrama, you will find something else.

That alone made me rate it less than I intended to, because it's not a direct adaptation, it copied a few elements from the original webtoon and the rest is new.

Now judging the whole thing starting with the changes in the story. Is it bad? Nope, not at all, I dare say it's actually a better story than the original, and if they were brave enough to ignore the source material completely and adjust the story a little, it'd be much better, hell, it'd be perfect.
Alas that it's not the case here, at some point I thought ok this is nevertheless, and in others I thought nope that's new, this state of confusion made me wonder how shall I rate this? Like should I compare it to the source or just ignore it?
To elaborate a little on this, some points that confused me a lot like the lack of attention given to the art, weird I know but they didn't explain what their arts represent, what does it means, I see some scribbles and they say wow! 🤯
Shall I be impressed now? I mean don't get me wrong but I'd appreciate if you explain more, how is this good art, why is this great, what did it represent?
Also the side stories that got disregarded after being completely presented in a very shallow way, if you don't want to show the side stories, don't! And focus only on the main characters story, I was surprised when Osakabe and Hikari disappeared suddenly, Ruki too was gone to give more space for the two leads interactions.
You don't have to burn the candle from both ends, if you can't show a character properly, don't make him a main.

So I believe the story could be much better if they just break free from the webtoon shadow, because them wanting to include elements from the webtoon (like the side stories and the main theme like the butterfly that didn't have any importance or influence on the ML nor did they give a reason of his love for them) was unnecessary.

Now I don't have any other complaints about acting or characters, the things they changed are acceptable and all actors did great.
I also - surprisingly - recommend it, if you are into this romantically melancholic stories and basically haven't read the webtoon.
