Ousama no Kyuujitsu

It's been eight months since Kakurai, CEO of a preeminent domestic apparel enterprise, last had a vacation, when he meets a pickpocket. That pickpocket turns out to be a young man named Kei. Upon meeting Kei, with his sharp, rebellious eyes, Kakurai's attracted to him, so he decides to take Kei along with him. At first, Kei acts like a wounded and cautious animal towards Kakurai, but then, seeing Kakurai's mature behavior and sincere attitude, he begins to open his heart. Will the adult who has everything―social status, reputation, money, etc―finally be able to encounter his true love for whom he'd throw it all away?!
