Be with You

Soo-ah, before passing away, makes an unbelievable promise to her husband, Woo-jin, to return one year later on a rainy day. Miraculously, she keeps the promise and reappears before her husband and son but all her memories have disappeared. Tragically, the relief at their reunion is short-lived, because it turns out that Soo-ah has to leave her family once again. (wikipedia.org)
