Irin is a strong woman that everyone in office is scared of, while Namcha is a vet in an animal hospital. One day, Namcha brought an injured snake to his hospital, which scared the female customer Ployjan so much that she fainted. Ployjan continued to annoyingly seduce Namcha as soon as she woke up. Namcha's sister called Irin over to help. Irin then successfully made Ployjan leave. In fact, Irin was previously in a relationship with Namcha when Namcha was still in high school. The two had a 7 year age gap. Back then, Irin thought Namcha was still a kid and decided to break up with him. But Namcha never forgot about her.
