Kimi to Lemon no Hoshi

A boy and a girl from different planets meet in a lemon orchard. One is a prince, the other an ordinary girl. Both should have been living happy lives, blessed with the love of their families, but... What awaits them is a sad, bittersweet, tearful first love... A bittersweet fantasy set on a planet about a boy and a girl who have lost a piece of their hearts begins!!
