Ten years ago, Yoon Seo saved the world under the name Seo Chae-yoon, but now he lives as an unknown hunter. He plans to die after fulfilling the last wishes of his deceased comrades, but these wishes are absurdly difficult, such as doing 3 million squats, catching ten 90cm red sea breams, and baking 10,000 choco crack cookies. One day, the global mega-guild Quartz merges with Yoon Seo’s guild and forms a new team. The world’s top hunter, Kwon Ji-han, immediately recognizes Yoon Seo’s unique qualities and approaches him. Initially put off by Kwon Ji-han’s arrogant demeanor, Yoon Seo soon realizes that he is a righteous and kind person. Having long abandoned notions of justice, Yoon Seo feels conflicted and restless around Kwon Ji-han. Haunted by his past from ten years ago and constantly reminded of Kwon Ji-han, can Yoon Seo complete the last wishes and find peace in death?
