Actress Shin Se Kyung had an opportunity to fangirl over actor and CNBLUE guitarist and singer Lee Jung Shin.

The opportunity did not happen in real life but rather in the April 16 episode of "Sensory Couple," also known as "The Girl Who Sees Smells." In real life, she is probably not as awed by idols, especially since her co-star in the drama is none other than JYJ's Park Yoo Chun.

She also appeared in the film "Tazza 2: The Hidden Card" with Big Bang member T.O.P.

In the April 16 episode Shin Se Kyung's character Oh Cho Rim has a chance encounter with an idol at a café. She can't resist asking him for an autograph. Lee Jung Shin played the idol in a cameo appearance. The scene was filmed at a Hongdae coffee shop.

Lee Jung Shin showed up for his scene and cheerfully greeted everyone who worked there as well as the drama's cast and crew. He said hello to Shin Se Kyung and Park Yoo Chun before the filming began

Several other actors also played the idol's fans but word of the shooting got out and actual CNBLUE fans started to show up at the filming site.

Lee Jung Shin did his one-episode cameo appearance because he is friendly with the drama's director Baek Soo Chan.

"Sensory Couple" is about two people whose fate is intertwined by a traumatic event. Park Yoo Chun plays a police officer whose sister was murdered in an as yet unsolved case. He became a police officer so he could solve cases. But his sister's death left him emotionally numb and somehow sensory impaired. Shin Se Kyung plays a woman who survived the murder of Park Yoo Chun's sister. But she was also affected by the trauma. Her senses were heightened to an extraordinary degree. They are so heightened it interferes with her life. But she can't remember anything about the murder.

Together they will help to heal each other while trying to solve the murder case. The key may lie in her lost memories.
