You can tell that Oda loves nami and luffy and wants them to be reunited asap.
I hope he is gonna give them more development and screentime after watching that godawful naruto ending.
I would not be surprised if Oda shipped Narusaku. I would not be surprised if Oda understood Sakura's character and knew where this was originally going and maybe that's why Kishi truly thinks goda as a friend because he really understood his struggles.
