When I explained the situation to my boyfriend, he was lying in his childhood sweetheart’s arms while eating an ice pop. He looked at me as if I were an idiot. “Your family is so poor that you can’t even afford to run the AC. Instead of looking at yourself, you came up with such a ridiculous excuse.” Later, I installed three air conditioners at home, but it did not help at all. In the end, I literally baked to death in an air-conditioned room at 60 degrees Fahrenheit. By the time I was discovered, I had turned into a dried corpse.
