What would you do if you had given up your life but life haven't given you up yet? When you wanted to die but ended up living a new life? When you wanted to leave because of unfair life but ended up loving someone from another world, another dimension? That question suits Iris Lee. She's a woman who grew up with no one beside her. A woman who lived her life all alone. She had enough of experiencing the world's unfairness but ended up living a new life, in a new world? A woman who would try so hard to keep someone who loves her by her side. What should she do? When she can leave that world anytime without knowing how.
