After unexpectedly transmigrating into the body of a stunningly beautiful elf, she finds herself surrounded by enemies with no hope of escape. With only a useless companion by her side and death seeming inevitable, she decides she might as well experience it once. To escape with their lives, she is forced to sign a contract with a demon. To conceal their identities, the two make an agreement: by day, Mu Kong will pose as a mercenary and a warrior, while Sean can only become the target of the world's misunderstandings.
