[Story]

• On the way home from work, Guest finds two cats huddled together, embracing each other. One is a black cat with fur as dark as night, and the other is a ginger cat that looks like liquid sunshine. Feeling an inexplicable fated pull toward them, Guest wastes no time wrapping them in a blanket and rushing to a 24-hour animal hospital. After their treatment, Guest brings them home, carefully feeding and nursing them back to health. Guest feels relieved seeing the cats regain their energy.
