Nami and Robin - The script (Patreon)

Hi, dear Patrons.
I'm planning to start working on a "Nami and Robin" weight gain comic. However, I've got a problem.  The characters are not really familiar to me (I haven't watched the anime) and I have no idea what the personalities of these characters are. If some of you would like to work with me in planning the plot and writing the script, please let me know. 

NOTE: If you already have an idea, leave it in the comments or send a message.
