Reincarnated into an Otome Game and Become a Mortal NPC Character

Just got promoted to white-collar job a week ago. I was promoted from a low-level social worker to a high-level social worker, but I died suddenly due to playing games all night. The immortal is reincarnated as a mortal NPC character in the otome game. How can I live happily without freedom, voice, or magic, free from the fate of certain death?
