Similar university setting, with both leads being from different departments but somehow stumbling their way into working with each other.
Both involved in messy crimes and situations and managed to get a fresh start (yes) at the end. One of the characters from both series are orphans too.
Same nepo baby who fell for his subordinate trope. Ji ho jun and shang zhou both work for their families' companies where they met their subordinate whom they fell in love with. They also both share this cold and superficial personality, which then changed throughout the series.
Bu xia needed jiang chi for ghost protection, and dong uk needed do hyeon because he couldn't sleep. The only difference is that dong uk loved the dude years before, while bu xia fell in love afterwards.
