Thanks for telling us.
I recommend Dimi as your character went to ask the bully to come over. That in your next post say how he rejected your offer and walked away. That would be the most natural thing to do. Than come back to the shop/table and ..go on with the story?

Well Ryusuke can easily be called over as in the old lady ordering something and she just go on with the plan of yours.

I have the feeling one more character isnt on the table to hear the old ladies invitation, or am I wrong?
