No they really do all have ruby I find it funny how they say she cursed when there the same lol
Spoiler!!!!!!!!
Her brother is not bratty he may seem that way in where we left off but shortly after we meet this bitchy lady who starts talking down to the MC and MC grabs her brother and runs away as she gets danger vibes from the lady. Later she does a magic trick with a handkerchief and her brother is ecstatic because he always holed up in his room he has always admired the magicians that he tried using their equipment but it broke.(〜￣△￣)〜
So he was made to fix them but he is also lonely due to being alone all the time after the Mc's performance he grows a deep admiration for her and calls her big sister!ヾ(❀╹◡╹)ﾉ~ Okay a little pause here, I am NOT fluent in Chinese but I have learned a few words one of them big sister recognizing the characters used in the speech bubble so that's how I know what he said. (๑•ㅂ•)و✧
So after that we have the two having a conversation and the mc and her brother go running around the MC starts goes running off to her butler/nanny and her brother rests and talks with the bitchy where we get a creepy segment where its showed she wants the boy to ONLY rely on her. (╬￣皿￣)凸
Other than that the mc and brother have a really cute relationship! ε=ε=(ノ≧∇≦)ノ
They say that her ruby eyes are cursed and all.. But no matter how I look I feel its similar to the eye colour of her daddy and that annoying bratty twin bro.. Maybe im suffering from mild colour blindness.. Well not that I care.. Afterall I come here for Levi
