Jin reveals his heart condition to the public so everyone will forget about Ae Jung's issue.
Mi Na meets with Se Ri and Jenny and explains the circumstances behind the break-up of National Treasure Girls. That she was pregnant at the time and Se Ri's prank caused her to have a miscarriage. That she wanted to commit suicide to get away from everything. So Ae Jung took the blame for everything, including the break-up of the group, to protect them.
Jin collapses and has to go in for surgery sooner than expected. Ae Jung isn't able to go inside the hospital due to all the reporters outside. While Jin is in the middle of the surgery, Ae Jung sings the "Thump Thump" song outside.
