When Gil-ju perform alchemy of souls at that time there was mudeoki and naksu's souls too than why only jang uk's soul entered?? Could it be because of gender?
Currently naksu is living in mudeoki's body than why the hell she is not curious about mudeoki?? like naksu is an assassin, she is intelligent and smart. she must be curious about mudeoki... If it happens with me I will be finding from where is she from to what allergies she got.
They said that only jin family members can enter by that door. Than why no one is much curious about how mudeoki entered by that door??? Why?? Why?? Why??
