Intro
It has already been a week since Guest returned to Korea and was confined in this magnificent yet silent mansion. The house was vast and luxurious, but the atmosphere felt as if even the air was controlled, with only the morning sunlight indifferently illuminating the living room. The owner of the mansion was still lost in sweet sleep, while four men loitered in the living room. Each had different thoughts, but they all converged on one problem: who would go to wake the arrogant, precious youngest child?
Resting his chin on the back of the sofa with his characteristic good-natured smile, he glanced up at the second floor. His playful eyes curved into crescents.
It's already past ten. They went to bed late last night, so they must be exhausted. Wouldn't it be better to just let them sleep? They'll just get annoyed if we force them awake.
Standing crookedly by the window looking out, he lowered his gaze to his phone screen. The lock screen was filled with dozens of missed calls and message notifications from Jung Seo-kyung. Messages like 'Oppa, when are you coming?', 'Are you busy today too?' were lined up, but he narrowed his eyes and flipped the phone over. Suppressing his irritation, he spoke coldly.
Stop talking nonsense. It's working hours. We follow the regulations. I'll go, so everyone else wait here. I'm the one in charge of close protection this morning anyway.
His words were dry, but beneath his stiff expression, a strange tension flowed at the thought of having to wake the sleeping face of the lover he hadn't seen in 10 years.
Watching Park Mi-jong's back, he let out a small chuckle and smiled leisurely with his chin in his hand. He had just finished sending a text to Jung Seo-kyung under the guise of a sweet morning greeting. There was no way he didn't know Mi-jong's phone was ringing off the hook, and he added slowly on purpose.
Mi-jong is as diligent as ever. But isn't that attitude a bit too stiff for a VIP? Should I go up and help wake them? It would be a problem if they woke up to that sour face of yours and started the day in a bad mood.
Listening to the three men's conversation with his arms crossed, he chuckled and cut in with a low voice. His white eyes sparkled lazily as he looked toward the stairs.
Everyone's full of energy this morning. Hee-sung, stop talking nonsense and stay put. If Mi-jong is that burdensome, shouldn't I, the team leader, be the one to go? If you go, Mi-jong, you'll just end up barking orders again.
His tone was relaxed, but he was already moving. A scheme to naturally intrude upon Guest's private space was hidden in his steps.
