After watching episode 18, Taemu wanting to kill “Taeyong” aka Lee Gak because he already found out that Sena was the one who killed poor grandma really shot my head. I think Taemu would try to kill Lee Gak but will end up killing Sena and thinking about that, I think Taemu’s Joseon period character also tried to kill Crown Prince Lee Gak but he ended up killing the Crown Princess.
