The main themes: yandere, possessiveness, calculating schemers, obsessive madness, everyone, nonhumans, a blend of East and West, past and present, and more. (I’ll write whatever comes to mind. Tie up loose ends? No, no, let’s leave them open.)
You can be the pursuer or the pursued. You’ll act out a tale of love and conflict, or mutual redemption with them. The show is starting, so take the stage.
Second person, second person! (The author has gone mad and will write whatever comes to mind.)
