Hey there, in case you forgot, she did risk her life and try escaping, thus met the beast once. The younger sister onviosly did more work, but let's also not forget that she had the goblin power, thus physically stronger.
I love the younger sister more, of course, but let's not hate the older please? And JeanneZoroLaw was right, she's in love.
But still, she could try to look for information about her sisters whereabouts. I mean, she is helping a prince (or someone with power), she could still ask them to help her inquire about her sister. But she does nothing the whole time but stay with him!, READING A BOOK!? what about the time he left and was not there?. Couldn't she again collect information about what is going on?. She is in another world for god sake!! And her sister is there too!
Nop, I understand she fells pity or is in love with the prince but her passiveness concerning her situation and her sister situation doesn't make me like her at all.
the older sister is seriously something else. it makes me so mad that she doesn't even try to leave while her sister is trying to do everything that she can to escape and find her (╯°Д °)╯╧╧
