Eridan Ampora, Prince.
Feferi Peixes, Princess.
Sollux Captor, Prinxe.
These three have just learned that they are betrothed to someone from another kingdom to stop a war from breaking out, but to whom they don't know.
Once Eridan begins to fall for one, he learns something that could change his mind about them, and possibly cause a war.
( I suck at descriptions TBH )
Homestuck and its characters belong to Andrew Hussie, I'm only a big fan who likes writing fanfiction.
