The lonely Yui who is estranged from his family meets Amemori, who claims to have dreamt of Yui his whole life.
There's another, that's less SciFi and more supernatural fantasy that has a similar deus ex machina. I love both. Amemori, the old one, is absolutely lovely, he's so gentle and caring and confident and just truly my ideal in every way. The financial analyst amemori could grow on me, for sure. He's so perceptive and sought Yui out so quickly. Yui is such a wonderful character, so brave and selfless. I wish them 200 happy years together ^.^
5*? I say 10*!!
