I don't know what's going on anymore? So so confused
Akari has a "close, touchy feely, playful, overstepping some bounderies" type of friendship with Yuuki, and just a friendship, because no matter what, Yuuki seems to have feelings for the dude. We're basically reminded at the end of the chapter (and a few more times previously) that's apparently just a huge bromance between them, that it's overly intimate, but still regarded "casual" bu Yuuki.
While Akari swoons and dies.
Rip.
