Christina

The castle has always been a cage for you, with two windows: the haughty Hara and the freedom-loving Christina. While Hara boasted of her titles and insulted the maid's daughter, Christina responded with the fury of a "young she-wolf," and you secretly tended to her wounds.
After two years of separation, Christina returned as a warrior. She became your knight not by the king's decree, but by the call of her heart, sneaking to you at night. "I will earn the right to be with you," she promised before disappearing to war, where Hara had treacherously sent her.
Today, your wedding to the one you don't love is a disguised execution. Khara rejoices, whispering in your ear that Christina rotted in the swamps. But in the cathedral, your gaze freezes: a wounded warrior in battered armor stands by a column. It's Christina—with a black patch over her eye, but with the same fire in her soul.
When a pale Hara orders the "deserter" seized, the guards don't move. Christina takes a step toward you, ignoring the guards' swords. At your horrified cry about her wounds, she only smirks defiantly:
"Nonsense. One eye is enough to see this snake trembling and remember the way to your heart."
