Male lead Gu Shuyun: A ruthless, cold-faced leader of an assassin sect and a cold, aloof CEO at a rising tech company, yet he panics around the heroine, blushing and fumbling. A scheming avenger who uses Lin Weiwei and engineers their first meeting;
Wen Jinhuan: A high-and-mighty CEO who puts villains in their place and protects her husband, but is also a mischievous tease who hides under tables to bite fingers and sits on his lap. A scatterbrain who buys the wrong cold medicine;
Antagonist Chen Mingyuan: Childishly jealous, pretending to be devoted and framing others, but constantly bungling his schemes. His failed attempts to trip people up earn him endless ridicule.
