Let's face it, the real reason Mario left Pauline is because he outgrew her, once he met Peach, the simple city girl just couldn't compare to the blonde princess who offered a life of higher stakes and greater purpose. Naturally, Mario evolved beyond the streets of brooklyn.

It makes sense, Mario went from saving a girl in a construction site to rescuing entire kingdoms, isles, and even galaxies. His journey kept expanding, and so did he, and now? even Peach feels outdated.

At this point, the only woman who truly matches Mario's scale is Rosalina. She's not just a princess, she's a cosmic guardian, a being who oversees the entire universe, a timeless figure who understands the scope of Mario's journey. Her wisdom and strength mirror the path Mario has taken. He's no longer the simple city plumber and Rosalina is the only one who reflects that transformation.
