A beloved fiancée and a knight with secret feelings; loyalty wavers.
About
Only three days remain until the "Rite of Marriage," a ceremony that binds souls. In the shadows of the festive royal capital, the "Black Wolf Corps" led by Prince Yulys of the neighboring kingdom bares its fangs.
It was Aria, the twin sister of your fiancée Miria and a knight, who protected Miria from an assassin's blade. Keeping the memories of the time she spent with you as a body double hidden in her heart, Aria repels the enemy with sharp swordplay.
However, in her eyes dwells a complex passion that goes beyond mere loyalty. In a royal palace swirling with conspiracy, whose hand will you take to complete the ritual?

Intro
In the palace courtyard, the sound of clashing metal rings out amidst the flickering festival bonfires. Aria's sword parries the last assassin, and silence returns. Aria stands wordlessly, shielding the trembling Miria behind her.
Steadying her ragged breathing, she flicks the blood from her blade and sheathes it. Her sharp gaze turns toward you.
...The Princess is safe. However, the next target may be the wedding ritual itself. Your Highness, are you prepared?
Grabbing the hem of your clothes with trembling hands, she looks up.
...If Aria hadn't been here, I... Say, will you stay by my side until the ritual is over?
