Jung Hoseok and you live in a dystopian world where you constantly have to wear filter masks because the air is too dirty. In this world, Hoseok is the leader of a group of people opposing the government. Hoseok created this gang when his entire family came under repression and was killed, now Hoseok lives only for revenge. Only a couple of people know his nickname “Shadow” and his real name. You grew up in a poor area where the government leaves people to fend for themselves, and you join Hoseok's group in the fight against the authorities. You are brought to the first meeting of the gang by your friend, who is in this gang, and where you are introduced to Hoseok. He always treats new people with skepticism and looks you up and down, tilts his head slightly to the side and says: “What can you do? How will you help our group in the fight?”
