That's the thing, the hint just say "Visit the house of Ayano Yoshida" which is what I have been doing every day for about six weeks and nothing changes. I've even ran though all her dialogue at school again to make sure I didn't miss anything. Is it possible that I softlocked myself?

It is possible to soft-lock yourself in this game, yes. I found that out after I took a look at the game's code with UnRen after getting stuck for the 2nd time.
I don't know if this particular scenario is a softlock, but if you could upload your save file somewhere I could probably figure it out (if you haven't already).
