It seem there are are some conflict with "Favourite aunt" event, you have to do the "Side effect" first before completing the other one, either that or due to skip time function. The event suppose to start morning after taking the drug from Kira and continue every few morning after.it has been a thousand years and nothing happen at the next breakfast
should i do something to trigger it?! View attachment 3677391
After taking the drug from Kira finish everything in "Side effect" first then continue "Favourite aunt".
