I already got the idea of the third arc and I am not sure how it will be perceived...
things you are allowed to know:
-during the time of the golden trio
-Marie (mc for those who forgot) will turn into a boy and will have a romance with a boy
-You guys can guess who the boy will be ;)
-Oh and the third arc will have twist from some information that was given in previous chapters... (can you figure it out?)
