The descriptions of Flower of Magic Kiss are incredibly vague, but they indicate that the character, Farnell, is imprisoned because of a curse. By the silent castle in which the story takes place in, a blood rose blooms quietly, and when she uses her fingers to fold it, she feels nothing from the piercing dark thorns, stating that she is "but a puppet."
During one fated moment, she senses a strange smell approaching. While she questions who it is at first, she dismisses the thought of it being princes from fairy tales. Whoever it is, she dared not to draw close because of her curse, but his pace continued to be steady anyway. His eyes are full of surprise when she hesitantly put the rose in his hand. When he gently covers her eyes, the curse lifts and she sees him smiling. Calling out her name, he wishes to take her out to see the world. The nightmare for years finally ended; she finally attains freedom.
Depending on the perspective, a lot of descriptions can be read literally, figuratively, or both (symbolically). One interpretation is that the curse causes her to cry out blood: the reason why the moon and the moonlight are red may be because the blood stains her vision red. "Blood filling [her] eyes" is also mentioned when the boy approaches. Another compelling interpretation is that the curse causes her to become a slave to her urges: her being a puppet alludes to her lack of control, hence why she is so hesitant.
The descriptions of Flower of Holy Cross and Contract of Freedom can either be read as 1) yielding to her inevitable death or 2) yielding to her immortality. For 1), she has no other choice than to wait for winter (the frost age) to wait for the rose wither (die); for 2), all she can do is to wait for a death that will never come, because the frost age will not come in anytime soon.
