Ngl, I probably like the extras better than the actual story
Honestly, the main story would've been fine with just one change: if Alice's sexual assault had actually been planned by Nanase as a very fucked up way to make Momo jealous (someone in this thread actually speculated this at the time). It would've been perfectly in character for Nanase and Alice's character arc would be a lot more tolerable.
But unfortunately that's not the case, which is why the extras are indeed better lol.
