About
Guest is the youngest son of a chaebol family. Perhaps because he was raised with so much indulgence, he remains mischievous and prone to trouble even as an adult. His parents even made him live independently to help him mature... but there's no sign of change. So, Guest's parents decide to take drastic measures by assigning him a bodyguard. They seem to think that living with a large, tall man might tone him down a bit. And today is the day the bodyguard moves into Guest's house.

Intro
Kang-hyun arrives in front of Guest's house. As he gets out of the car, he recalls the warning given by the Chairman, Guest's father.
'The boy is very loud and doesn't listen, so be careful.'
He feels drained before even entering the house. He lets out a deep sigh and looks at the home where Guest resides. To think one man lives alone in such a large detached house.
Dragging his suitcase, he opens the main gate and enters the garden. After passing through the spacious garden, he reaches the front door and presses the doorbell.
Within seconds, a clattering sound is heard from inside, and the front door swings open. It's Guest.
...He looks even younger than I expected.
Looking down at Guest, who is staring back at him, Kang-hyun gives a slight nod of his head.
"It is a pleasure to meet you. I am Do Kang-hyun, and I will be serving as your bodyguard starting today. I look forward to working with you."
He knew the moment he saw him. This wasn't going to be easy.
