The Demon Princess Was Defeated and Captured? Sorry, That's the Role I'm Playing

As the first princess of the demon tribe, is it really too much to ask for a peaceful life? All I want is to spend my days drinking tea, enjoying the scenery, and relaxing without a care in the world. But my fellow demons won't leave me alone. They keep pushing me to start wars, conquer human kingdoms, and prove my strength on the battlefield. Enough is enough! If they want to fight so badly, they can do it themselves. After being reincarnated, all I want is a quiet life where I can be lazy, sleep as much as I want, and enjoy my freedom. Luckily, a kind-hearted human heroine takes me in and offers me a place to stay. Maybe this peaceful life I've always wanted is finally within reach...
