At this point I'm reading this in a sunken cost fallacy kinda way. I need to see how it ends, but I'm not invested in how it gets there. Which sucks because I really liked the original premise.
And it sucks for basically everyone involved in this love hexagon in some way or another. You've got Mei who's basically just being moved around by a carrot on a stick by Maria, Riri not being to let go because of Mei's selfishness (which was partially brought out by Riri being manipulative even if unintentionally), and Maria, Minato and Kaoru who just can't be honest with their own feelings and in Kaoru's case decided to run away as a coping mechanism.
The only one who's getting anything out of this ultimately is Karin who turned out to have trauma, and managed to snap out of that freak funk she was stuck in.
And I'd be okay with it if we even got some time for the situation to get there, but the pacing is just constantly breakneck, gotta speedrun the confession olympics within 2 or 3 chapters, and even within these 2 or 3 chapters, maybe half of the final one, if that, is dedicated to the confession and ensuing rejection. You can't even go "oh yeah okay that makes sense" because they're trading 3 or 4 sentences and it's over. Touhou games somehow have more properly resolved conflicts even though all the characters who aren't the playable ones have anywhere from 5 to 10 lines of dialogue.
