Everyone on the Thousand Sunny knew that Nami was his. There was no doubt in the matter. Luffy was the most accepting of their relationship, with the warning that he would be beat up if Nami was hurt, of course. Zoro reluctantly agreed to their relationship, although Law did get pulled aside by him one evening to discuss them. Sanji eventually agreed, with minor tears and whines. The others agreed with minimal problems, Robin having been their wing woman back at that bar where they first got to know each other.
When Law asked Luffy for his blessings to marry Nami, no one batted an eyelash. Okay, that's a lie. Franky did, as he cried loudly, saying something about true love.
Law had planned the proposal very carefully. The next island they were supposed to land at was known for its romantic sunsets, and there was a cliff on the western side of the mountain, where there would be a perfect view of the sunset, and also the golden beaches below. Law would lead her up the mountain, and when they arrived at the top, he would propose.
Law had already prepared a 215 carat gold ring, embedded with spessartite, and a diamond as its centerpiece. It was stunning!
When the day came, Law led Nami up the mountain.
"Where are we going?" Nami asked, curious as to why she was being led up the mountain. "Is it our anniversary or something?".
"You'll see once we get there, Nami-ya." He replied.
"We're almost there, anyways. Why can't you just tell me now?"
"Yes. We're almost there. You can wait."
"Fine." She huffed.
"We're here." Law called out over his shoulder.
"It's so pretty~" Nami said, gazing at the orange sunset in awe.
"Just like you." Law answered back, then cringed, thinking of how lovey-dovey that was.
Nami giggled, pressing a kiss to his cheek, and grabbed his hands.
"Nami. You are the best thing that's ever happened to me. I love you so much. Would you do me the ho-".
"TORAO, NAMI ARE YOU DONE? SANJI SAYS I CAN'T EAT UNTIL YOU COME BACK! HURRY UP!" Luffy bellowed from the beach below.
Then, noticing that the two were on the ledge, he extended his rubbery arms, and grabbed the two of them. Nami shrieked, and Law held in the urge to scream- both in anger and fear. Although he would fervently deny the latter.
"MUGIWARA-YA! YOU JERK!"
"LUFFY!"
