The Seventh Prince Wants to Bail

At the end of a grueling day, a sudden pain struck—and I found myself transmigrated into the fantasy novel 'Dark Header!'

However, the events of the original story began unfolding far earlier than expected. As I move between the imperial palace and the slums... a covert effort to contain the fallout begins.
