A 24-year-old woman traveled to the novel world due to a plane crash. She takes over the body of a cannon fodder who bears the same name as her. She traveled to a time when everything was scarce. The moment she opened her eyes, she was told that in two months, she would marry a lame man.Flustered girl : “Why didn't anyone tell me that my fiancé is so good-looking?”Proud fiancé : “Baby, I'm glad you like my face and body. Shall I warm your bed now?”Confused girl : “Didn't they say you are a cripple? How can you move so vigorously?”Vigorous husband : “Where did you hear such rumors? It seems that I need to prove myself to you.”Shy girl : “So shameless...”

She was stupidly in love with him. Because of him, she became rude and unreasonable, overbearing, jealous, insane. But he did not spare a glance to her. Married for two years, he didn’t favor her once, letting her become the laughing stock of the whole world. Eventually, she ended up in an affair, leading to her tragic death.

As their souls linger on the edge of the afterlife, a mysterious force intervenes, merging their fragmented souls together with a new being. Rusty, the living armor, now affected by their memories and presence, embarks on his own quest. Will he seek revenge on those who betrayed the hero, or will he fulfill the desires of the fallen demon king? or instead, forge his own path?
