While I definitely ship her more worth the prince, it seemed to be implied that he doesn't want a relationship right now because he's still upset/mourning his dead fiance. Mind you, it's only her speculation but she's been pretty spot on so far. Still, I would love a story where she becomes friends with Cadio only and helps the prince overcome his grief and trauma. Losing someone who took their own life has to be extremely hard.

i know end game is most likely cadio x mc, but goddamn i really want her to get w the prince T-T dude got friendzoned badd
