>>30621327>>30621220MaleMC is just as fictional as FeMC with Lillie.
Lillie dumped him and left for Kanto to travel alone.
Alola isn't her home, and she'll set up permanently wherever her mother goes when she's out of rehab. If anything, after doing her Kanto trainer routine and nursing her mother for probably 2-3 years, she will go to other major areas of the Pokeworld, instead of the place she's already too old to do the 11-year-old trials at.
