A young outsider who has become a trophy of her own. This is the current position of Eunhyo, the princess of Haewon, who has become the concubine of the crown prince of the divine nation. The young princess, unable to trust anyone, had to quietly hide her sharp claws to protect her fragile self. And always by her side is a presence that protects her. "I will gladly become your everything." Transcending status, bloodline, and gender, the only bodyguard who resonates with Eunhyo's heart is Danwol. "Thanks to you, this hellish place feels somewhat like paradise." In the dark, unfamiliar sky of a foreign land, a red moon rose brightly in Eunhyo's heart, which had been pitch black.
