Jun Ji Hyun transformed into a caterpillar while trapped in the sleeping bag.
On the 9th episode of SBS Wednesday/Thursday "You Who Came from the Stars" broadcast on January 15th, Chun Song Yi (played by Jun Ji Hyun) was caught in the green sleeping bag.
On this day, Chun Song Yi kissed Do Min Joon (played by Kim Soo Hyun) and he opened a window to let the fever down as she went into the sleeping bag.
Do Min Joon who got energy said to Chun Song Yi, "Be quiet. My head hurts" and he was cold.
At this, Chun Song Yi was upset saying, "That's some way of talking to someone who stayed up all night nursing. Seeing how rude you are, you must be better."
Afterwards, Chun Song Yi tried coming out of the sleeping bag but the zipper was broken and she was crawling like a bug.
Netizens who saw the broadcast said, "Jun Ji Hyun, caterpillar great acting, was so funny." "Jun Ji Hyun, caterpillar, like a real caterpillar." "Jun Ji Hyun, caterpillar, so cute."
