Just do Ayano Task it's keep going even the task still stuck like that,I restart this game almost 175 time with 175 save data just to find out the game mechanic,so on my theory Ayano and Yuuki quest are similar even after you pick the agitated on Yuuki Oota Storyline it will continue to Ayano Task like task to be Ayano best friend and then you became deputy of Occult club and smth like that
NT:Sorry my English bad af I hope you understand what I mean
