How to trigger the last candy in the Princess Crown (PSP), that is, the task that requires local cooking?

1. Every time you go to a new place, as long as there are pubs and bakeries, you have to buy food once and eat it all. When you talk to a young man in a private house in the north, you will help him find the broken arrow. When you find him, you will tell him the last hotel location. After you buy a meal (you don't need to eat), you will get the last candy when you talk again.

2. I didn't eat the demon juice at first because it would deduct my strength (exchange half HP for strength), so I didn't find the task of breaking the arrow in the end, so I went back to ride for a long time before I finished it.
