I know, it's not like they are blood related, but a 15 (?) yo. in this outfit shouting "I'm papa's wife" would obviously make her real mother lose her marbles. I was originally doubting if she was actually her mother, but skin color, fashion sense and aerodynamics check out, so I think it is true.
What about Mina then? Are they only half-sisters or not really related?
It becomes increasingly clearer why this manga is so low rated.
The conflict writing feels so terrible and monotone (and other things ofc).
Does that make me quit? Apparently not.
