I watched the 1st season (remake) and a few episodes of the original.
The new looks like a compressed version. Some newer eps have stuff that happens in two episodes in the original but keeping it as a single episode (not like 2 in 1 episodes).
The artstyle is different
The humor was updated but I’d say similar.
It feels like how the total content compares between a manga and the anime adaption (meaning some stuff or stories were cut)



IMO: Light hearted ecchi but also romcom.
I’d say it’s enjoyable for the former viewers but it’s like watching the movie adaptation of a book you have read.
