Revise the ending.

I don't like the ending, and yes I do have an alternative ending in mind. I was actually typing it, but accidentally navigated away. I don't feel like retyping all of that, so instead of getting all the detail plus the sides I wrote, you get a TL/DR (sorry).
Zin successfully sends Idris away from the palace unnoticed, Zin reports back everyone is dead, Zin and Idris have reunion at Bellet Mansion, blah blah, embrace as sun rises, roll credits on main story.
Side summaries. Side1: Idris is recovering, Zin seeks disguise for Idris, princess wants to talk about coronation/marriage. Side2: Princess and Zin get married, Zin escapes after wedding and returns to longer haired BLONDE Idris (the invention of hair dye), Zin makes Idris the new head of the Bellet guards and gives Idris a new name. Side3: Empress (formerly princess) sends people to bring Zin who has been avoiding her, they finally have the heir talk. Zin balks, Idris reassures. Empress and Zin arrange baby making schedule. Side4: Empress and Zin's baby is born with blonde hair and purple eyes, they name him Klyne. Stuff with Idris, such as talking about baby, physical intimacy with eachother, yada yada. Side5: Couple years pass, Zin is reading letter from disabled former Idris squire, the guy used the money Zin was sending him to study and has opened an apothecary where his sister sells the medicine he makes. Butler comes in, reports Zin's brother has had a baby with his wife, Zin orders to prepare congratulatory letter/gift and also notes that the marquisdom should probably be left to his brother's children as his son shall be inheriting the kingdom. Zin prepares for day out with son plus Idris. Story should end with happy family feels (also, Idris smiles). The End.
