Let’s get each other out of here.” The boy, who didn't know who he was or why he was trapped, felt a desire for the first time. “Can I stay by your side forever?” The boy, who grew up as an emotionless human weapon, now dreams of getting out of prison with the fairy. Through a single method. “I will be your soulmate. Let’s make a contract.” Original Webtoon:
