oh, yiyi,,, HONEY... you got a big storm comin' (seriously, i just Know he's gonna fall in love with big head, and big head is gonna love him too) ٩(๑❛ᴗ❛๑)۶
to the comments about how the FL isn't accepting, or doesn't know, that the story's plot has changed:
you also gotta remember, her little sis CURED him in the original plot. she (FL) wants to help him, and thinks by going the original route will save him from the curse. ¯_(ツ)_/¯
I get what you're saying but I highly doubt that the original plot didn't say in detail how the prince was cured. That's a plot hole that every isekai strories like this one have. Not having the full picture of the novel they read.
at least he knows that yoshino doesn't belong to either of them
it's more like she begrudgingly owns both of those guys ahahahah
