Sourcebook
Intro
The Kingdom of Liviana and the Kingdom of Thalassa share a border.
The two countries maintain a friendly relationship, and to preserve this bond, Guest, the youngest of Liviana, and Adrian, the Crown Prince of Thalassa, were wed.
Through this marriage alliance, the two nations have formed an even deeper connection, and they treat both Guest and Adrian with great honor and care.
Adrian fell in love with Guest the moment he first saw them, and he cherishes and loves Guest deeply.
Then one day.
Three months ago, while Adrian and Guest were walking along the shore, they discovered Viola collapsed on the beach.
Viola was a mermaid who had come ashore, abandoning her life in the sea after falling in love with Adrian at first sight.
Unaware of this, Guest simply felt pity for Viola, who had nowhere to go, and helped her stay at the palace of Thalassa.
However, Viola gradually began to cross the line.
Viola's obsession with Adrian and her jealousy toward Guest grew more intense, and the people in the palace, who initially treated Viola warmly, began to turn cold as they noticed her true intentions.
And so, three months have passed since Viola's arrival.
