Hmm speaking as someone who is aroace (though I don't claim to be the most informed), this was okay, I guess? It's not something I would rec, but I don't hate it either. The two leads honestly don't have much going on for them. A goal or something for Yuriko would've been nice since it felt like she was just along for the ride. There was some missed opportunity for a proper conflict about Matoi being in love with Yuriko and her being unable to reciprocate, since it was just resolved with Matoi deciding to defer to Yuriko's wants. It generally felt like they kept making the perfect choices for each other, which is fine, but it doesn't make a very compelling narrative. Like, screw a up a bit!
I like best girl Rio as much as the next person, but I don't think a relationship between her and Matoi could've worked out in the long term. It looks like they want different things out of a relationship, with Rio favoring physical touch while Matoi seems indifferent to it. Although they could always talk it out, I guess.
