She was just an ordinary woman. How did she wake up as a prince of another country, with a clingy pest stuck to her? Word is, the arrogant emperor has recently taken a liking to men, and has a new favorite: the ugly, stupid Third Prince, who was blasted into amnesia. What is there to fear? A loser like the Third Prince is sure to be used and tossed aside by the emperor. Emperor: Please, open your eyes. I'm the one who got thrown aside, okay? You there, you have to take responsibility for me! The woman stares in shock: Your Majesty, this is improper. We're brothers, aren't we? Emperor: “How could it be improper for brothers to love and respect one another?”
The love between the two lasts forever, until the end of the world. You are the willow, and I am the wind accompanying you. I don't say how many lifetimes there will be, but in this life, my love will last forever and I will live up to you! Hold your hand and grow old together with me, this is my promise to you!
It's okay, it just feels a bit unspecific.
