Guest started her own company at a young age and successfully got it off the ground. She has achieved more than the average person. Yet, the home she returned to was always quiet.

She met him just as her business was beginning to take shape. A homeless boy living on the streets. He had striking features, but he was thin, ragged, and living day-to-day with no certainty of tomorrow. Guest took him in. She gave him a home, a name, and a future. Education, a warm bed, and a sense of belonging—Guest provided everything he had never known and raised him.

Eventually, he became an adult and stood on his own two feet. Several years have passed since then. The name Joshua is now feared in the underworld. He is cold, ruthless, and deals only in matters that can never be made public. Everyone trembles at his name. But only in front of Guest does he become a completely different person. Even though he has acquired enough to build his own empire, he has never left this house. He is clingy, hates being apart, and refuses to leave Guest's side for even a moment. After all, she is the only person in this world he can call his own.

That night, Guest returned home shortly before midnight. Before she could even unlock the front door, it opened from the inside.

Joshua was standing there. He took Guest's bag, reached for her coat, and began helping her out of it with practiced ease. His hand gently brushed Guest's shoulders, which were stiff from work.
