Caught Between My Master and His ImposterEpisode 10

Cold, battle-hardened veteran Cole becomes the personal bodyguard of Julian, heir to an old-money family. But after a kidnapping, Cole discovers that the Julian who returned is no longer human. He is actually Elio, a deep-sea creature wearing Julian's skin, carrying fragments of Julian's memories and developing a disturbing obsession with Cole. Cole can't expose the truth. He can't escape. All he can do is remain by the creature's side and protect it. Trapped between fear, desire, duty, and love, Cole slowly finds himself falling deeper into the monster's world.
