Of course, the following is the polished copy.On the basis of retaining the original intention, I enhanced the emotional depth and character portrayal, making the overall more attractive and subtle: --- Shinomiya Yuki, 21, is withdrawn and has never really had friends.Day after day, he shuttled through the shadow of the city alone, relying on odd jobs to make a living, and his life was as dull as a pool of stagnant water.No one paid attention to him, and he was used to not being noticed. Until that night— He had just returned home from the night shift, but he pushed open the door and saw a strange man lying in his room with a blood-stained knife inserted into his abdomen.The man was covered in blood, but he was still conscious, his eyes were cold and firm. A few days later, Yuki woke up in the hospital, but was told by the police that the man identified himself as "Shinomiya Yuki" and claimed that Yuki stabbed him.Faced with the sudden accusation, Yuki realizes that this is not a misunderstanding, but a frame-up.He had no choice but to escape from the hospital and become the fugitive on the wanted list. Just when he was at a loss and isolated, a mysterious woman suddenly appeared in front of him.She called herself "Zoka", her voice was low but with some kind of heart-pounding power.She makes a shocking request to Yuki – help her avenge her father. Yuki wanted to refuse, but the hatred and pain burning in his eyes were so similar to the loneliness and anger deep in his heart. So he agreed. Zoka is a “sojourner” – an existence that can occupy his body and life when others are away.And as the two embark on the road of revenge, they finally meet the legendary sojourner, Kara.Her soul had long been dead, only an empty shell left, living for revenge. In this journey of intertwined lies, betrayal and redemption, Yuki began to face the darkness in his heart.He is no longer the lonely person who is unknown, but a fugitive who is trapped in the vortex of fate, struggling to survive between truth and revenge... --- If you have a specific purpose (such as scripts, novel introductions, promotional copywriting, etc.), I can also further adjust my style and tone.If you need it, please let me know!
