I need a straight hate to love type of romance where their dynamic still continues even though they’re together

This kind of give off the energy ur looking for I think

Starts when they were like a child??
isekai supposedly they will divorce
pink hair fl
forgot the color of ml’s hair
og fl is the third party here, she is a princess
mc basically handled the kingdom while ml was on the war i think
ml and princess are shipped by their comrades and they are the og ml and fl in the supposed novel they are also in the same base and stuff
fl found out she is sick
the guard who preaches for the princess hates fl until he found out that she was sick and she is actually nicee
there was another guy who likes fl?? which is a blondie i think?
also princess here was actually a white lotus i think??
i hope someone will knows it
