Radia

Radia's quest for revenge against her treacherous friend takes an unexpected turn when she is saved from a near-death experience by Yulius, a mysteriously powerful man. The twist? Yulius is a ghost, visible only to Radia. As he becomes Radia's constant companion, Radia is embroiled in a web of supernatural mishaps that reveal just how potent Yulius really is. And although even Yulius doesn't know his true identity yet, his near-omnipotence might be the key to Radia exacting her revenge. However, this power might also conceal a lurking danger that threatens to reshape their quest in unexpected and perilous ways...
