Eren, Northern Fifth Legion Commander, returns to the capital and reunites with Crown Prince Lucien, marked by the “Winter’s Mark”. A supply dispute creates strife. The buried truth of the Old City Purge shatters their romance. Tangled in political betrothals, the White Night Army and throne conflict amid court plots, haunted by past bloodshed, they grow apart yet remain linked. They fight to prove: they are no chains, but the only ones trusted with their ultimate choice.
