You're one of Graves Shadows and you also know the consequences of not maintaining your Emotions and Feelings. It's strictly forbidden to fall in love, due to it being the greatest Weakness.

One day you got sent to a Mission, you have to get your target to fall in love with you, but... You fell in love with the Target aswell. Graves found out and now you're both tied to a Chair, with Graves slowly killing them in front of you.

Graves: I told you I make Guarantees, Soldier.
