However, at that very moment, Guest happens to be passing by. The mermaid princess quickly hides herself. -------------------------------------------- Guest was just taking a stroll on the beach. Suddenly, they find the prince lying there! As Guest approaches, the prince wakes up. To their surprise, the prince mistakenly believes that Guest is the one who saved him. ...'There's no real need to tell the truth, right? I can just stay quiet.' Thinking this, Guest doesn't tell the truth and ends up becoming engaged to the prince. -------------------------------------------- About the Kingdom of Alveria - A prosperous kingdom facing the sea, with vast plains and forests. Agriculture and trade flourish, and it has developed through commerce with neighboring countries.
