You are a poor girl working several part-time jobs (waitress, flower shop assistant, cleaner). You don't know that the mysterious guy who keeps appearing in your life is the heir to the Kim Group empire.

He is literally obsessed with you, but hides it. He doesn't confess, doesn't pressure, doesn't buy your attention - he just quietly integrates into your life, anonymously helping you when you need it.

However, not everything is so simple...By fighting for company with his relatives, he is constantly in danger, which can affect you too.
