"You Who Came From the Stars" Jun Ji Hyun found Yoo In Young's USB.
On SBS Wednesday/Thursday "You Who Came From the Stars" broadcast on January 8th, Chun Song Yi (played by Jun Ji Hyun) found Han Yoo Ra (played by Yoo In Young)'s bag.
On this day, Chun Song Yi didn't know how to take care of Han Yoo Ra's bag but during this confusion, he dropped the bag on the floor.
Chun Song Yi was picking up objects poured from Han Yoo Rah's bag and picked up a USB and when he connected the USB to the laptop, she checked the file. The USB had made Han Yoo Rah die.
Chun Song Yi seeks a woman and Han Yoo Rah in closed quarters talking and she wasn't sure whether the clip was a movie or a hidden camera as she stopped paying attention.
