I feel like this story would have been so much better if either:
1: they stay as father and daughter and stop all the romantic stuff or
2: They didn't put it into my head that they are father and daughter at all. Although i know its not biological and they just met so there is no previous affiliation, so it's not weird for them to fall in love especially given their situation, I JUST FEEL SO WEIRD ABOUT WATCHING THEM FALL IN LOVE UNDER THAT TITLE! I'm not even concerned about the age gap or anything as to that's a common thing in manga, its just weird.
if they has it so that the grandpa adopted her instead, idk i would have felt better about this. but i guess that would have changed the story too much idk
OMG this is awful XDXD
