Silhouette Montevero decided to step down from her position as a secret agent to live a normal and peaceful life, not worrying about anything nor her own safety. She's already living the life she wished for when a powerful group ruined everything. In one snap, she's suddenly surrounded by seven mysterious people convincing her to join a high-rank organization led by Third Knights.
Upon joining Delta, one of the most prestigious agencies around the world – she found herself being curious with their leader who started showing interest towards her.
After spending more time with him through their missions, she finally realized she had fallen already. Yet after spending good times together, Silhouette’s past still bothered her a lot.
Especially after finding out that Third has something to do with her family’s massacre years ago. Disgusted and surprised, that's all she felt after confirming that Third was the one who caused the massacre that happened to her loved ones.
She did everything to stay away from him, to shut him out of her life, but nothing’s stronger than her love for him. She knows that no matter how much she pushes him, she’s still hoping for another chance.
True to her words, she did everything to confirm once again if he really did such a horrible thing. And after finding out a secret file on his belongings, she finally found out that Third is not the mastermind of the massacre.
All along, it was the agency she trusted for all her life. After reconciling with Third, they finally had the chance to have a peaceful and happy family.
