At first, I thought that fully regressing would've been better because I thought that all the girls would just remain nonexistent. But then they showed that there were other Dreamers (that's what I'm going to call them for now). That changed everything. This is actually much more interesting. The problem is how fast the events are taking place.
If it was me, I would delay Chono and Asakura realizing they are the same. We barely got over that and now there's another girl who's about to find out the truth. All of this happened in a matter of 10 chapters. We barely got any fluff as there should be in any romcom ever. I'm okay with plot but damn author needs to chill, no one is going to take your pen away dude
