I'm still learning some of the fundamentals of events. I've searched for the answer to this problem, but I haven't found a successful solution yet.
I have an event in which the player walks over a tile and a NPC approaches the player and asks if they want to help. I have this part working. However, if the character says 'No', I would still like the option for the player to manually approach the NPC to have another chance at answering. How can I add this functionality to my existing event?
The event so far:

Thanks
