^for the mother's role, i understand .. but just like every normal sibling, parent would also say that older should always give way to younger with a reasonable reason. however, in this case, aum have fallen for him that's why fighting over her own problem .. if she have not fallen for him, i'm sure she'll move way b/c she knew all along that Yui have the biggest crush and love for Weir .. if i'm in her show and known this, i wouldn't have pursue weir either, it was kindda selfish of her even though there's no intention of doing it. -- as for Weir, he tells and so he needs to stop doing all these good stuff toward her .. it show that he have a little something toward her especially when she have the biggest crush on him .. and like i say, it's also Yui's fault for believing what the officer said -- i really think it's best if the two sisters end up with no weir at the end !
