I wish that, instead of using the tired trope of the 'love interest and psychotic lesbian childhood friend duo', we had something more interesting that actually makes good use of the MC's telepathy.
Imagine if they acted the same way (for the most part), but their actual thoughts didn't match.
For example, Sawari still acting the 'popular cutie who's into the MC for some reason', but her thoughs revealing she's pretending, maybe has been for a while, for some reason or another - maybe to stop getting bothered by other boys courting her.
And Sonoda actually having a crush on Yonemine, but having chosen to hide it for Sawari's sake, completely unaware of the truth of her friend's feelings.
Now there would be some interesting potential for telepathy-related shenanigans.
