By the time I reached thirty, I hadn't managed to provide any of the happiness I wanted for my wife.I also still couldn't become the support my parents relied on.At this turning point in my fate, my income suddenly began to increase randomly.(A daily life tale in a wealthy family setting, featuring a single female lead and no harem.)

[Matured Content]Isadora Skaldwood was born a fae of impure blood “mannfae” deemed an inferior creation of the olden gods. However, at birth she was kissed by the goddess of light and blessed with the ability of a skin weaver, capable of healing any wound or affliction.Betrayed by her family, she's sold for gain and shipped across the world to a brothel, into the hands of a selfish businessman who exploited her abilities for years. Travelers come to this brothel not to lay with the rumored mannfae but to seek her abilities—the star price of the famous brothel in the countryside.But then everything changed when “He” appeared…Kraven Val Thrond “The Reaper” of the Raven Court, a terrifying warrior feared by those who dared to speak his name. Dangerously handsome with looks identical to a god, silver eyes like the crescent moon—but a mind dipped in madness.Isadora despised him, not just for stealing her away, but for thrusting her into his world of blood and chaos—taking her freedom just like everyone else does. He’s insane! But that’s only the cherry on top, his obsession is wicked.(Excerpt)“You want to kill me and at the same time, you do not” Isadora’s features were stern and the cold look in her eyes almost forced a laugh out of him.She got more frustrated by his silence, choosing to insult him and be done with it. “Does a madman not know what to do with a mannfae?”“I can think of a thousand ways to kill you,” Kraven replied in a velvety voice. “Like first throwing you off-board”Isadora's angry expression morphed into one of horror.“But that would be terrifying, wouldn’t it? Drowning in the dark sea, unable to breathe” he voiced as if he could vividly picture it—and him on board watching. “Tell me, Isadora”A cold chill crawled down her spine.“If I let you go, where would you run to, hm? I told you already this realm isn't kind to outcasts like us”“I'm not like you!”He chuckled lightly. “We're alike. What use could you be to this forsaken realm?”“What use could you have of me?” she asked shakily.“Oh love, I can think of many things but I’m not sure you’re ready… yet”
