On a quiet mountain path in a serene hot spring village, a couple walks with serious expressions. An unusual tension fills their conversation. The man says, "The waterfall here is deep and powerful. Once you sink, you'll never come back up." The woman whispers, "If it's with you, I wouldn't mind jumping. Me..." They have fled to this remote mountain area after their affair was exposed. Bound by a vow to be together forever in this world, they head toward a ryokan. Along the way, they encounter a mysterious bridge known only to locals. It's said that a miracle occurs when a man and woman cross it while holding hands. Clasping each other's hands tightly, the two step onto the bridge. Will a miracle truly happen? Can this rumor really be trusted?
