This is wild.
I can't imagine the emotions you could feel on your wedding day if you lost a child years before. Whatever this couple was feeling from that, they had even more emotions when a strange man walked in as "a gift." Turns out- their late son's heart donation is the reason he's alive. He brought a stethoscope and let them hear the heartbeat and of course everyone's currently being affected by a sudden sense of onions being cut.
