thx @overlord for pt 2 of the rp plot!
PT 1:The Humans and The Mer kingdoms have always lived in peace… until now, the heir to the Mer's throne has been kidnapped by the human ruler, and the only way to prevent war is to return the Mer's heir to the Mer kingdom. The Mer's have sent a negotiator to convince the human ruler to return the heir by a specific deadline, but as the deadline draws closer the Mer's grow more impatient, from the heir not being returned and the ever-growing pollution in their waters. With the ruler of the Mer's patience running thin, they are at the brink of declaring war.
PT 2:The war has begun and Character A has discovered that the mer-prince has been forced into an arranged betrothal to the human prince, a way to trap the mer-kingdom's air since, once kissed by a human, a merperson loses their scales and becomes trapped on land. The Mer-king is old and greatly weakened due to a previous injury, with his time drawing nearer and without an heir to inherit his throne, the mer-kingdom will collapse. Character A must navigate through the obstacles and find a way to free the prince without inciting further violence, a difficult task for any young person to handle. What he does not expect is to fall into an illicit romance with the cool and confident human prince (who kinda gives me like-Todoroki vibes-). Falling for the prince more and more with each passing day, his feelings begin to cloud his judgement ...and the romance between them only makes finding a way to end this war more difficult....
