:

Su-ji collapses in Sun-young's arms, and Sun-young takes her to the emergency room. Hyun-sung and Su-ji's family head over to the hospital as soon as they hear the news. U-ri visits her later on, but Hyun-sung warns him not to cross the line and sends him away. The next day, Sun-young stops by Su-ji's ward to get her food.
