An elderly woman always goes up to the mountain on Thursdays to tie a knot on a sacred tree, as a vow. The road is long and impracticable and the woman walks wearily with her walking stick, trying to not fall into the deep snow. Although she is tired, she is determined to go on. One day, near the sacred tree, the woman meets an old man who had been her admirer many years earlier and who can now finally declare his love for her, even if thirty years have passed since that earlier time.
