Equilibrium

'When the boy – Luffy, was it? – comes up to him after the wedding and tells him very seriously that he will kill him if he ever hurts Nami Zoro snorts and tries (and fails) to explain to him the concept of arranged marriage. Luffy doesn't get it. He just picks his nose and dubs it a mystery thing.' - ZoLu, small mentions of ZoNa and LawLu
