Yeah but he is still her bitch tho.
and he is still the generic isekai boi here whether or not the noble princess took him in,
his training was just..."I trained hard for 500 years and am now a very strong impotent monk kicking ass in another world."
It's just a cheat with extra steps where god gives him immortality and he trains for 500 years,
but after all that he doesn't really act like a 500 year old.
Now with the marriage with flat knight girl he is sure to be shackled permanently to her family, like a djinn.
This is why I hate isekai that starts as them being nobles or when they aim to be nobles, the adventure there gets killed.
too many laws/rules to follow and isekai mc being a beta cannot say NO!
this is just a rant tho, not saying this is shit tier but I hate where this is going
