What? The story has been pretty easy to follow though?I would hope this arc gets over soon to give the author a fresh reset into the next one. Its pretty clear from the multitude of pople always asking about the plot that the story is kinda jumbled up to this point.
Faust is an isekai protagonist who gets thrown into a genderswapped world and becomes a famous war hero who is coveted by the royal family. He doesn't want to marry any of them because his lands will be absorbed into their kingdoms amd he wants to retain his sovereignty out of respect for his mom. He joins Valerie because he hopes that with her low positiom he can live a quiet life defending his kingdom in peace.
The entire main political plot of the story is one hilarious misunderstanding. The queen wants to ensure a smooth succession for Anastasia so that her daughters don't fight. Valerie feels like she is always playing second fiddle to Anastacia so she strikes out on her own to recruit Faust. Anastacia is in love with Faust and wants him on her side. The queen thinks Anastacia and Astarte despise Valerie so she wants to take Faust away to protect Valerie from being killed in a succession war between the sisters. Meanwhile Anastacia and Astarte actually care a lot about Valerie and don't hold any ill will towards her.
