Before my crazy grandfather died, he gave me three walnuts and asked me to crack one open on my twenty-fifth birthday. As for the second walnut, he asked me to break it open before we got married. The first one is to go under the overpass and kowtow three times to the first beggar you meet. My cheeks felt hot, but I did as I was told. It turned out that the beggar was an undercover police officer. Later I found out that I had already been targeted by human traffickers, and kowtow saved my life. When I was about to marry the policeman who saved me, when I opened the second walnut. Inside was an old photo crumpled into a ball. My fiancée was laughing and strangling the other groom. And the groom's suit is exactly the same as the one I'm wearing.
