I Will Be the Main Character in That Prison

'In the afterlife, I hope to be reborn as a rich man's dog.' Yujin is orphaned and unable to find a regular job. While thinking about being a rich man's dog, she is hit by a truck and enters the game Golden Cage! She finds herself possessing a little gray-haired extra who is killed by the prince at the beginning of the game. Not wanting to live a life struggle, she decides to take the place of the game's heroine and become the prince's pet dog... "Woof, woof, woof!" By barking like a dog, she succeeds in attracting the prince's attention and gets a job as his 'dog'! Eugene earns the title of "puppy-sama" and is given a cushy puppy life... but the problem is, the crazed emperor, who was obsessed with whether the "dog" would run away in the original, is not so obsessed! "What's wrong, my dear Yujin?" Instead, he just looks at her with warm eyes... Awww, maybe I should have pretended to run away. Yujin's struggle to enjoy a cozy and comfortable life as a dog!
