The night before our divorce, my wife and I were only a single thought away from ending our marriage. But with a clap of thunder, I time-traveled to ancient times. Even more absurdly, the little white dog barking at me non-stop turned out to be my wife! From a small rented apartment, we tumbled into a penniless, broken ancient courtyard. To survive, I started a workshop and fought bullies; while she, who once refused to say even a single soft word, shielded me time and again, and even took a fatal blow for me. Only at that moment did I understand that we weren't no longer in love, but simply exhausted by life of the strength to express love. Yet when the chance to return to modern times finally appeared, I didn't dare ask her: Is that undivorced agreement still valid?
