I recently watched Kotonoha no Niwa, real heart warming story!! I absolutely enjoyed the movie as a whole and adored the Tanka which was in it.
"A faint clap of thunder, clouded skies, perhaps rain comes, If so, will you stay here with me?"
"A faint clap of thunder Even if rains comes not I will stay here Together with you"
Really really good anime movie, if you haven't seen it I highly recommend it!
