Explore Rosemary Mansion

Go to the left, and go through the upper door. In the next room, go to the left and go through the upper door again. Then in the next two rooms, go through the lower-left door. Follow the path from there and open the gift box to get a Life Up Cream, then go to the upper-left of the room and check on the piano to learn the next Melody.

If you don't feel like collecting the items in the mansion (Bread, Life Up Cream, and two Antidotes), you can just leave. Otherwise, go back the way you came until you are in a room with two chairs and a table, then go through the door on the right. This is the first room of the mansion. Go through the lower-left door, then go through the lower-left door to reach a room with an Antidote. If you want some bread, go through the upper-left door and follow the path, using the lower-left door on the way, to find the Bread. Then go back the way you came until you reach the room with the gift box, and go through the lower-left door there. Then go through the lower-left door to find an Antidote and go through the upper-left door to find a Life Up Cream. Those are all of the items that you can find here, so you can leave. Just keep going to the right until you have left the mansion.
