Ren YuEpisode 4

Synopsis

One missing girl. Three very different lives. As the search pulls them together, each girl faces a choice that could break her—or save her. Above ground, the city gleams; below, a maze of dark tunnels hides its secrets. One girl walks that line alone, through pain and buried truths, until she uncovers what really happened. But finding the answer is only half the fight. The other half? Finding herself, and a way back to the light.
