Abyss Trap: The Bewitching Mistress, 30 Ep. Free
Helen was paid to enter the Hai villa as a mistress, her job to hold Arthur back so he would never sign a certain contract. What she actually does is go through his father's old sea logs every night after he falls asleep, because the ship that went down in that typhoon three years ago was carrying cargo that should not exist. Arthur's fiancee Winnie is the real siren, and her singing can put a ship on the rocks and rewrite a will.
