If you score about 200+ for haruka mini car game, not only does it not increase the relationship points from 0 it also says haruka relationship points is max out while having 0.
Tried loading other saves to restart the talk and go for the mini car game and it can somehow bug to other saves making it haruka relationship points is max out while having 0 after the mini game. So unable to talk to her cause it keeps saying max relationship points while still 0.
