The Twin Affair

“I never should’ve let him have you! You belong to me!” He snarls at me, his voice possessive, authoritative; high spikes of jealousy in his tone. * I fell in love with my husband’s twin brother in high school. It's been five years now and I still can't stop thinking about the Twin that got away. The actual love of my life. When he unexpectedly returns from Europe, our chemistry is stronger than ever. I can’t resist him. Axel, the bad boy. A single touch from him sets my skin on fire. “Tell me you’ve never thought of me all these years. Never even imagined for one second about me,” he rasps. A question that I'm too ashamed to answer. I know I married the wrong twin. But worse than that? I can’t stop fucking my husband’s twin brother under his roof.

Changing The Princess's Fate

Changing The Princess's Fate

I am Angel Lim. An avid fan of a popular novel called, 'The Angel They Adored'. It was a reverse harem story where countless men fell in love with the heroine. It's a great masterpiece but I always hated it whenever the greatest villainess harrases her. Yes. That's what I thought before reading the last chapter of the novel. It was the dying moment of princess Ledecia and for the first time, she reminisced her life. "Why did I even exist in the first place if all in my life I'll be in pain?" Those are the last words she utters before dying. And It was very painful. *Knock knock* I paused my thoughts when I heard a loud knock coming from the front door of my apartment. "I'm coming" "Delivery from lily's shop ma'am" I opened my door as I slowly approached the man standing before me. "Oh sorry? But I didn't---" realizing what he said, I immediately tried to said that I didn't order anything but my words were interrupted by a sudden pain. A sharp thing, pierced through my stomach I groaned as I see the blood flowing from my chest. How unfortunate. I wish I had treasured my life more. In the middle of losing conciousness, my honest feeling came out If I'll have the chance to live once again, I'll live free and happy. But then when I opened my eyes, I was transported into Princess Ledecia's body - a villainess from my favorite novel!
