In the beginning, Yeonjun the Red Fox and his crew sailed the seas for freedom alone. Yet when a young widow implored him to lead her to a fabled treasure, how could the captain deny such a plea?

When the flames of battle began to lick the palace walls, Lee Yesa fled. She encountered Kai in the midst of their escape. Together they wove a journey and shared sparks of warmth. But war forced them to bid farewell. For the sake of fragile peace, Joseon prostrated itself before the enemy. The last of the bloodline was sent as tribute to the nation that had burned their homeland. And in that foreign land, Yesa once again gazed into a pair of eyes that had once promised the warmth of protection. But Yesa no longer knew who she was facing. Was this man still a friend, or had he transformed into a foe?

Park Yebin thought her life was already in shambles. She had lost her family, been labeled a traitor, and was now trapped in a gisaeng house. Her only goal was to survive, keep a low profile and quietly wait for a chance to escape. But all her suffering suddenly seemed trivial the moment Choi Bomi arrived, a new gisaeng who tripped over her own hanbok, held musical instruments like weapons, and had a gaze like she was ready to punch the king. When Yebin accidentally saw Bomi undressing and cursing in a deep voice, she realized one thing, she wasn't just sharing a room with an ordinary gisaeng, but with someone whose very existence could shake the entire kingdom. And if the crown prince rumored to have died was actually alive, his enemies would not sit still for long.

Amid the bustling Lantern Festival in Hanyang, Kang Taehyun accidentally encounters a girl dressed in a hanbok the color of cherry blossom petals. Her presence feels so tangible, yet as fleeting as a shadow that could vanish at any moment. As if bound by the threads of fate, they meet in the same place every year. Yet, the deeper Taehyun tries to understand her, the more mysteries surround her. Who is this girl, and why does she appear only on the night of the festival?

No one dared to approach Choi Yeonjun within a 10-meter radius, except for a crazy first-year student named Choi Beomgyu. While everyone else refused to get close to Yeonjun; the young man whose piercing gaze always felt like a blade. Beomgyu; the beautiful-faced boy, boldly demanded the dorm supervisor to assign them to the same room. He wasn't the least bit afraid, even though Yeonjun looked ready to kill him at any moment. Beomgyu was clearly not sane. And that madman managed to make Yeonjun lose his sanity as well, constantly accusing him of being involved in someone's murder and threatening to ruin his life without any evidence or clear reason. So, what exactly drove Beomgyu to make such accusations against Yeonjun?

Park Yerin is consumed by loneliness, but she's not as alone as she thinks. Choi Soobin is always by her side, silently watching over her like a shadow. However, Soobin fails to recognize the truth; the shadow he casts is far lonelier than the person he follows.
