Ohhh omg that is plausible. Because he's shown interest in her from the beginning, the youngert twin couldn't have known of her since he was in the monetary.
Also he knows a lot of things and has connections? Like, how did he knew about princesses lover? And reached out to help him (probably to piss her off)? How did he know he was abused??? Thats something that her fiance could have known, but not a guy that was stuck in the monastery from a very young age
This is my fave theory yet, holy moly you’re a genius
Newest updates here also show him refer to his dead brother at the grave as only brother, never calls him bishark, probably to awkward calling his dead brother by his own name. But easier to refer to him as bishark to others. And the face he made when Keisha wore red??
Hear me out: ML is actualy the dead brother. He faked his death to pursue FL and get away from the princess. He killed Coby beacuse he could recognise the younger twin since he knew him really well.
