He took my mother’s life, I took his wife

Leo, 22, appears to be a "useless young master" crushed by his father, but his true identity is the "Shadow Monarch" — founder of the world's largest mercenary group and venture capital conglomerate. His father Victor murdered Leo's mother years ago to seize the family fortune, and has now taken the stunning 25-year-old Elena as his new wife. At a lavish banquet, Victor publicly humiliates Leo while showing off his beautiful young bride. To reclaim everything his mother lost and avenge her death, Leo decides to target Victor's proudest "trophy" — his gorgeous wife Elena — and launches a meticulously planned campaign of revenge and conquest.
