I haven't read the exact novel, but generally in such 'returned from hell' themed novels, the protagonist might have gone through some kind of ordeal in hell, gained special powers or knowledge, and then comes back to the real world to seek revenge or make changes. Maybe Han Dae Sung in this novel is on a journey to right some wrongs or face his old enemies with new - found strength.
Since I'm not very familiar with this novel, Han Dae Sung is surely one of the main characters as the title implies. There might be other characters like his friends or foes. Maybe there's a mentor - like figure who helps him adjust to the world after returning from hell, or there could be an antagonist who tries to stop him from achieving his goals.
The plot mainly revolves around Han Dae Sung who returns from hell. His experiences in hell have likely changed him in many ways, and the story probably follows his new journey in the world he has come back to. It might involve him facing challenges, using skills or knowledge he gained in hell, and interacting with various characters in this new phase of his life.
You can try to find it on some popular light novel platforms such as Webnovel or NovelUpdates. They often list a wide range of light novels, and there might be a chance that 'Han Dae Sung Returned from Hell' is available there.
There were two main reasons why Lu Han's " Medal " couldn't be sung casually. First of all, the copyright of this song was restricted. Without the authorization of the copyright owner, the song could not be performed in public. This was to protect the copyright of the song and prevent unauthorized covers and transmissions. Secondly, the theme of this song was about soldiers and honor. If the theme of the concert had nothing to do with this song, it might not be appropriate to choose to perform this song. In addition, during the concert, the singer might adapt the song to suit the theme and atmosphere of the concert. If the song " Medal " wasn't suitable for adaptation, or if Lu Han felt that other songs were more suitable for concerts, then he might not have chosen to sing this song. In short, there were many factors to consider when singing Lu Han's " Medal," including copyright, the theme of the song, and the feasibility of adaptation.
One common theme is adventure. They often go on quests or face challenges together. Another theme is friendship development that might turn into something more romantic over time.
