ALTER EGO - EP.01

She’s not a hero. She’s not a villain. She’s something far more dangerous than both. . . . Hongdae. A quiet afternoon. Until the sky cracked open — and something dark came down. A shadow colossus rose from the destruction. Nothing could stop it. Until NANAappeared. Beautiful. Young. Innocent-looking. But something inside her refused to stay silent. An entity. A second soul living inside her body — beautiful, sadistic, merciless. One that doesn’t just fight back... It enjoys every second of it. But this isn’t just NANA’s story. There’s something bigger. Something darker. A force powerful enough to possess anyone — from the inside out. Who sent that darkness to Hongdae? And can NANA control the entity within her... …or is it already the other way around?
