Shyvana Question

Shyvana having a professional relationship with the person she guards J4. Considering she is her closest bodyguard and all, would she be defiant or act in negativity/refusal if J4 and Quinn got married (hypothetically)? Or would she continue her duties as she does now? Would she be upset etc?

And how would the noble women in Demacia feel? Upset? All those countless noble women who wanted a shot at the crown.
