If Lee Kno
Honestly it's definitely a red flag in my case it's kind of selfish that he wants Lee Nok to die and give up living the rest of his life but if Lee Nok is willing to do that then
The guy goes full red flag since the very beginning.
He does say that but he actually doesn't want the prince to die lol. Also I think he said that because he doesn't really understand the worth of human life since he is a ghost.
I think he meant that he(jaeshin) will wait for him(lee nok) to die in his time and then take him(lee nok) with him(jaeshin)
Mm i wouldn't say is green or red, but is important to read between lines he is a ghost so he dosen't see the problem in taking him to the after world to live with him, i think he got that idea after seeing the ghost girl with her lover, he dosen't understand the humans lives, he dosen't understand their feelings.
In many ways he's still a young boy experiencing his fist love because he hasn’t realize that he's in love with the prince and is selfish but that dosen't mean he actually wants to harm the prince, we can see he's helping him.
That is so true! He's never lived a human life before! You're so smart
Is it a green flag or a red flag that he loves the crown prince so much that he wants him to die so he can take him to the afterlife?
