I used to be a homebody, and I ended up trapped in a cruel world

After dying from overwork, I opened my eyes and found myself inside a romance-fantasy genre…?! Of all the bodies to inhabit, I ended up as the royal proxy of a princess—even though I just wanted a quiet life! No meals because I’d be sleepy, no sleep because there was work to do. As the princess’s ruthless employer, I spent sleepless nights awaiting the day I’d collapse from overwork—only to be kidnapped (or so it seemed) at last…? But what kind of kidnapping is this that feels so comfortable? They feed me, let me sleep, and even give me money…! Thus begins a haphazard life of captivity with the kidnapper, Duke Blaire! Can I, once a K-office worker and now the princess’s “slave,” break free from death by overwork in this life… and preserve my comfy imprisoned existence?
