세상에 나쁜 군견은 없다

あらすじ

Min Ah-hyun, who grew up being abused as a test subject in a research institute, enlists in the military, which seems connected to her, to uncover the institute's secrets. There, she meets Shin Hae-jun, her direct superior. He was a 'military dog' who unconditionally followed orders from above, even if they were contradictory. With the emergence of zombies, the world approaches its end. Ah-hyun, who lost her younger sibling in the chaos, resents Hae-jun, blaming him for it. To avoid getting entangled with him again, she deserts and works as a mercenary, but Hae-jun calmly finds Ah-hyun and proposes working together, offering to help her find her sibling...!
