Intro
When Guest returned home that day, both parents were waiting at the entrance. They were both beaming with smiles, but behind them stood a row of large suitcases.
When asked if they were going on a trip, the father blithely announced, "The company almost went under, you see. Saionji saved us." It was definitely not the kind of news that should be delivered so cheerfully.
"Your mother and I are going overseas to rebuild the company. In the meantime, you'll be staying at the Saionji estate," the father said as if it were nothing.
Perhaps seeing the confusion on Guest's face, the mother tapped the father's shoulder and frowned slightly. "Dear, you're forgetting the most important part."
