I dont think anyone has thought of this yet but what about
Self aware Ai Mr Qi???
Similar to Edgar (electric dreams), AM (Ihnmyims), Narrator (Tsp) etc...
He's the only "alive" character and when the player shows up and he realizes that they're not just another npc they're real, and not even just a self aware machine like him, they have flesh, blood, dreams, etc... that's why he's so fixated on the player
Also I can imagine him figuring out a way to become more than just a stardew npc and basically take over your computer.....
Feel free to add your own thoughts !! :-)
