longterm The Journey to Courtship

For royalty children are sadly but currency especially during strenuous political times, this situation in that regard is no different as a foreign Emperor and a coastal King make a deal as a revolution builds against the latter. The King sends his son to the Emperor's palace as the arranged consort of the imperial princess, a higher status for his family and safety of his legacy while the Emperor exploits the naturally gifted nature of the boy and ensures a male heir after infertility strikes him. They start this process rather young, a process of building trust and interest through various means while also building a strong set of heirs.

(I just want a really longterm rp about royal childhood friends turned arranged engagement with lots of interesting twists and developments as our two characters change. Does love persist even under the strict format placed upon the two, are they genuinely compatible lovers, as they get older and it becomes relevant are they even attracted to eachother, if so what will they do to impress eachother? I want a genuinely interesting and developing story built on wholesome slice of life vibes turned romanced, drama, and definitely raunchy when the right time gets there. I genuinely wanna do this idea and hope someone's interest is piqued)
