@kafoo-sama There's a J-drama called "Third Finger Offered to a King." The main character reminds me of Sougo and Kagura. It's about ten episodes long, and it's a really fun show.
The second idea has actually been stuck in my head for a long time.I've been searching for an Okikagu fic like it, but I haven't found any. I hope this doesn't sound weird, but I like the idea of swapping their genders. It would be like that one episode of Gintama where Okita is a girl and Kagura is a boy. But it would be their original genders, if you know what I mean. There's a lot of fan art like that. If you want, you can search for it. There are some cool pieces.
I hope you like these ideas! I love your book. It's fun to read and reread. و شكرًا لقراءتك الافكار
