No Go Jin is a rude CEO, who treats everyone around him like trash. He doesn't care about the well-being of his employees as long as he gets his work done. He cannot empathize with the people around him, repeatedly causing emotional pain to his employees. His eccentric personality is a result of his traumatic childhood and his failed relationship. But in no way can it justify his repeated abuse of his employees.

Later he falls in love, and with guidance from his girlfriend, he learns to understand the cause of his actions and later repented with all his heart. But in the end, no amount of repentance could bring back the times lost and the emotional pain his victims went through.

The entire story is built up with misunderstandings. His secretary finds out she is terminally ill and she threw all the blame for her stressful life on her boss, NGJ. Later she finds out that her CT was mixed up with someone else in the hospital and she was perfectly healthy. Afterward, NGJ gets into an accident and he pretends to have amnesia to catch the one who attempts to murder him. Thinking he is amnestic, his secretary pretends to be his fiance. At one point his ex-girlfriend comes back and wants to win him back. But NGJ repeatedly rejects her, blaming her for the breakup. But later he finds out that she left to protect him. In the end, NGJ's bestie tries to destroy his company misunderstanding that NGJ killed his sister. Like this, every misunderstanding snowballed into a huge mess. This pretty much sums up the story.

Although I watched it until the end, because the overall story is weak, I won't recommend it to anyone to watch.
