Edward Newgate, more commonly known as "Whitebeard", was the captain of the Whitebeard Pirates and was widely known as the "Strongest Man in the World" and, after
Nami and Usopp are the two strawhats Luffy has the closest relationship with. This isn't disregarding the other strawhats as not being close, rather this is more like the two Characters Luffy is always seen around.
Including the Yonko, Luffy is already the closest man to the One Piece, having two out of the four Road Poneglyphs already. In comparison, both Big Mom and Kaido have one Road Poneglyph each, which just goes to show that Luffy is already closer to the greatest treasure than they are.
1 Whitebeard, The World's Strongest Man
Captain of the Whitebeard Pirates, Whitebeard was one of the strongest pirates of Roger's time. With the power of the Gura Gura no Mi and an incredibly strong Haki, Whitebeard was known as the strongest man alive. The only person strong enough to equal him in combat was Gol D.
At least two have fallen in love with him, Alvida and Hancock, whilst another two have become enamoured with him, Rebecca and Shirahoshi. Nami, Robin and Vivi all share close and deep bonds with Luffy and have become some of his closest friends.
When will One Piece end? Oda continues to estimate when the final plot will be delivered but pushes those dates back in favour of more content. His most recent predications suggested One Piece could potentially conclude in either 2024 or 2025 but given the show's history, nothing is set in stone.
In 2014 he estimated that One Piece would last 10 more years (until 2024). And in 2020 he predicted about 4 or 5 years to go (again, 2024 or 2025). The roadmap seems clear, although you never really know since there is so much story left to tell and the characters keep moving and evolving.
starting with the first kiss shown in one piece it happened during the story of thriller bark where luffy and the straw hats go to thriller bark to defeat moria. and retrieve the shadows that were taken by it during episode 365 absalon takes nami hostage.
That said, there is one crew member who stands above the rest in terms of loyalty to Luffy: Roronoa Zoro. The Straw Pirates' first mate has proven his loyalty on numerous occasions throughout the series, even putting his crew mates' well-being above his own life.
Throughout his journey Luffy has made strong bonds with numerous women. At least two have fallen in love with him, Alvida and Hancock, whilst another two have become enamoured with him, Rebecca and Shirahoshi. Nami, Robin and Vivi all share close and deep bonds with Luffy and have become some of his closest friends.
Kuina is not only Zoro's first friend, but she's responsible for the man he is today.
Roger's first and perhaps his most formidable rival and greatest enemy was Rocks D. Xebec, the captain of the legendary Rocks Pirates who sought to become the king of the world.

1 Wano Country Arc - Ongoing
The Wano Country arc is the longest one in the anime so far, with over 110 episodes already and the end being nowhere in sight. Like most One Piece arcs after the time skip, it suffers from pacing issues as well and, at times, draws the content from the manga out a little too much.
Zoro x Hiyori
The Wanokuni arc of One Piece gave Zoro the spotlight he deserved but fans were more gravitated toward his scenes with Hiyori. It wouldn't surprise fans if Hiyori reveals her feelings for Zoro, her savior. They shared intimate moments and Zoro might even find a sense of belongingness when he's with her.
[One Piece] Luffy Gets Married with Hancock_2.
On the day after Zoro and Kuina made their vow, Kuina had fallen down the stairs and died.
Whitebeard, on the other hand, easily equaled Roger's power. Even Garp called Whitebeard "The King of Seas." So, it is beyond any shadow of a doubt that Whitebeard could have defeated Garp in a fight to the death.
In the Post-War arc, one of the Five Elders stated that "D." means danger. After the timeskip, Law mentioned the Will of D. once more when Doflamingo asked him why he had so much faith in Luffy. After visiting Laugh Tale, Kozuki Oden mentioned that he and the Roger Pirates had learned the meaning of the D. name.
It is evident that the only person capable of surpassing Roger is Luffy. Even though Luffy still has a lot to achieve, he is the only person who can transform the entire world.
