Special Forces: Fire Phoenix, Her Instructor

She is an undercover agent for the military. He pulls her out of hell, and she joins the Fire Phoenix training camp.

He is her instructor, the only person who knows everything about her past.

He falls for her first, but never says a word. She realizes her feelings later, and by the time she does, it's too late to hide them.

She takes a bullet for him, and he takes a bullet for her too. At the prisoner-of-war training camp, he pulls her back from the brink of collapse. Her love helps him overcome his guilt.

The day before their wedding, she disappears. Eight months later, he storms the K2 base and brings her back.

She is the person he personally pulled out of hell, and the one his gun has never once been aimed at.

He is her light and hope, and also the sharpest blade in her hand.
