Thanks, I've made a lot of progress, what I still feel stuck is with Dea, she's already in the palace, I've already built the temple, I already got the scenes of Sara with the ninja in the basement, but I don't know how to make it happen in the bathrooms... ., the secret hot spring is already unlocked... I don't know what else to do to trigger the S event:
Another thing that I think happened to me because I was sleepy was, what happened to the queen of Begus, I remember at the beginning that you visit her, but then no mission was activated, I returned to the castle but she is not on the throne, in There is no more information in the guide, and it also mentions that after meeting her, more missions with secondary characters are activated, but I have no more clues.
