Lots of loopholes and unrealistic or incomplete ending scenarios like how was the great Aunt killed,why the main villain woman wasn't arrested by the police after the allegations,billions of debt was left behind by the great Aunt so what happens to it & her firm, In-Kyung's boyfriend plans to go to U.S when his grandfather is sick earlier he mentioned he wanted to spend time with him, what happens to the villains goons(guards), so it's a 6/10 for me
