JB was sent to the emergency room after a car accident, and Haesung and Rian both were in exploding tears.

In KBS 'Dream High 2' aired on March 13th, JB gets in a car accident while trying to save a kid that was running into the road, and gets sent to the emergency room. Haesung, who witnessed the car accident, was in unstoppable tears in front of the surgery room.
Rian, who hears about JB's accident, runs to the hospital.

Rian finds Haesung crying in front of the surgery room, and yells at her, "You said you like him, you said you'll protect him. Why did you make him like this? You don't even have a right to be here. Stay away from JB!"

Yoo Jin (Jiinwoon) tries to stop the fight, but Haesung leaves the hospital and Rian alone stays at the hospital by JB.

Though the doctor says it's not a big injury and that JB will be fine, Haesung locks herself in a room in guilt and depression. Even with Yoo Jin comforting her, Haesung cannot dare to visit the hospital again.
