Well, from the story so far, Arima loves Yuki, Yuki actually likes Arima but doesn’t want to tread on Miyahara, and Miyahara doesn’t seem to have the thought of love in her head at all (we don’t really know yet).
The story will probably either end with Arima changing his mind and confessing to Miyahara (and perform a reverse title drop)… or end with Miyahara realizing her feelings and asking him out instead. A brave ending would be Arima and Yuki getting together and Miyahara still being close to both of them.
Probably no hope for Yuki.
