On the day we divorced, I was packing when I found my wife's ledger. Alongside the daily expenses we'd tracked from the days when we had nothing to where we were now, she had kept a scorecard for me. From the first day we started dating, she'd recorded in red every little thing I'd long forgotten, awarding me ten or twenty points at a time. But as the years went by, the deductions grew more and more frequent. At the very end, I saw a sentence she'd written in black ink: “He's not the Ji Heyan who loves me. Minus 100 points.”
