aaA tbh I was kinda confused about that too?? tbh i'm an avid stalker of kokoroten's work and i actually bought the japanese novel for this and am slowly working my way through it as well- but from what i can see from the art she draws of aoi and sakura as well as a few pages towards the end of the novel, they did indeed like each other and are the 'real ship??' like.
//novel spoilers//
you know that tree sleeping scene at the end of the game? in the novel, it was sakura instead if i'm reading this right
but that still leaves me pretty damn confused on where hinata and aoi stand with each other, esp with the while incest-y thing since they clearly see the other as VERY important in all forms of media, but... sighs
