si yo estaba igual es que tienes que ser el jefe del pueblo primero y despues habla con ella para activar el evento yo tambien tuve el mismo problema y me puse hacer la historia para activarlo
Karyn's event should be activated now haaaa I remembered after you become chief of the village go to the sakura tree and interact with her then wait a while and when you're ready go talk to her in her room and now with the Lycoris clan I also hit do not punish and after seeing what happens I loaded the game to see what happened if I punished her and it's the same the difference is that the girl called luna stops you and they give you a sermon and that's it for the moment that the continuation comes out I will write it in English so that it is easier
