I Saw You in My Dream – Kisskh English Subtitle

On the last night of the sixth and twelfth month each year, Ai has long had prophetic dreams. There’s only one thing he’s never dreamt of—love. On the last night of that year, however, he dreams of a love so warm. He doesn’t want to believe that the man of his dream could be P’Yu, a neighbour skilled at driving him crazy, the opposite of dream Yu.
