Akira knows for sure Yuuto love her, but still cling to Kai despite he seems to already forgot about her... she's so hopeless now realising Yuuto would be there for her despite her quirks...
Good that Yuuto is such a honest guy, otherwise it would go sideways for both, him satisfying his lust but not love and her being used but never get love she can't get...
Hopefully it will be revealed why Akira so much yearns of love, this shit ain't normal at all...
Edit: Dunno why, but although Kai did save Yuuto from the bullies, him not being in stable relationships tells me something is off about him and isn't as "nice guy" he seems to be...
Thanks for the scanlation!
