My Father's Perfect Lie - Episode 1

Mom's panicked warning opens the episode: she urges young Nina to run, claiming Nina's father and grandmother want her dead. Nina, terrified, demands why her dad framed Grandpa and killed everyone in the Chancellor's Mansion. The father appears, ordering obedience—he'll spare Nina if she complies, or kill her and her mother if she doesn't. Nina pleads about her tenth birthday and accuses him of killing his wife for a concubine. Overwhelmed, someone offers their blood and vows revenge in another life, shouting "I'm reborn!" The episode ends on that blood oath and Nina's uncertain fate.
