I think the teacher might win. My prediction is that all of the confessions will end up with some issue that needs to be solved. Karin’s problem is that she uses kissing to forget and essentially kisses anyone. My prediction for everyone else is that Riri-Chan has some issues with intimacy before marriage. It may be due to her being an idol or coming from a conservative family. In one chapter, Minato completely rejects another girl and says something about love being impossible for her. I don’t know her issue, but I don’t see her ending up with Mei because of this clue. Kaoru seems to have a problem giving in to desires from her long speeches despite giving in to her desires when she sniffs Mei. That is probably why she hasn’t confessed. (This could be a reach, though Kaoru seems complicated)
The only issue Maria has is that her position as a teacher hinders her ability to go further with Mei. She seems fine with waiting for her and having her experience other relationships. In the end, if they’re both single, I’m sure she would accept her as a girlfriend. I wish I knew where the ex crush came in the picture. Maybe she’s being used as a tool for Mei to figure out which girl she likes the most.

Bro lots of people on Dynasty hates aces seems like. Everytime they appear it's always a trainwreck in the comments. Empathy isn't in abundance around here I guess.

More like hate imo, I think it can give a "no resolution" feeling? Im aroace so I dont see it that way, but people I know when they see stories like these, they tend to expect for a "romatic story with a sweet kiss closing the relationship" (me too just in case, I really like stories like that but I understand this ending too and I like it); since (in a really cruel way to say it) for them it was like if there is not kiss is just all a "game".

No I think everyone’s just hornee. I’m the least ace person but I really like seeing this kinda relationship play out it’s refreshing and sweet for a yuri story.
