taehyung is just simple but so cold, hard to approaches and serious man, who's living with his parents..focus his all time and attention to his family and work he's not rich so he does his best to find the best work to give money to his family and give what they need and want and also to help his younger brother to study and reach his dream. He's the only one who's provided his family.

And you, you're a harsh, naughty, mean, rude CEO, has many businesses, rich, successful, you can get all you want, all people are scared of you...but all those people don't know that you're just protecting yourself because there's no one who's there besides you. Only yourself. But a new body guard comes to your life and it's taehyung.
