This can't possibly end well. I am not invested in OP ships but the following two are something I wish to see even if it is non-canon. Okay, here goes nothing:
- Luffy x Margueritte (They both did plenty for each other and clearly Margueritte is attracted to Luffy's sincere nature)
- Zoro x Vivi (Mr. Bushido needs to stop)
In seriousness, Luffy x Zoro bromance (no romance, no yaoi stuff) at EoS would be welcome too. Those two continuing their adventures together without their trusted navigator would be f**king hilarious.
