Thank you so much for the review! We're super happy you're enjoying the game <3
As for your question...
SPOILER***
Alexis won't ever choose to remove the petals in any of the endings, since the only way to do that requires too much sacrifice.
In Serin's bad ending, they will accidentally remove them temporarily, but will forever lose their magical abilities afterward.
Of course, if we ever explore this world a bit more with Alexis, we're sure they'll find something that can be done~ But for now, Alexis will bravely choose to live with them :D
