Actress Go Youn-jung made a special appearance in the Disney+ series The Lighting Store (directed by Kim Hee-won), leaving a strong impression despite her brief screen time.

Go Youn-jung appeared in the post-credits scene of the final episode released on December 18, making her debut in a police station scene after the story had concluded.

Her character connected to the Moving universe (directed by Park In-je and Park Yoon-seo), reprising her role as Jang Hee-soo, a college prep student, and a witness to the Jungwon High School collapse incident.

Her regenerative powers were hinted at during the scene. When a detective (played by Bae Sung-woo) asked if she was injured, Hee-soo casually responded, "I don't get hurt," with an unfazed expression.

According to her agency, this cameo was made possible through her connection with director Kim Hee-won, with whom she worked as a student-teacher duo in Moving.

This also marks her second collaboration with writer Kang Full. Go Youn-jung gained global popularity through Moving and has won several awards, including at the Blue Dragon Series Awards.

Meanwhile, Go Youn-jung has been cast in the upcoming Netflix series Is This Love Translatable?.
