Aiden had always been a good kid. Brave. Fearless. The kind of boy who couldn't turn a blind eye to injustice, no matter how small. It wasn't in his nature to walk away. That's why, on his usual route home, when he saw a group of men trying to snatch a woman's bag in front of a bookstore, his body moved before his mind could catch up. He charged toward them, fists clenched, heart pounding-not out of fear, but out of instinct. But good deeds don't always end well. He barely heard the woman's scream as cold steel pierced his side. Once. Twice. Over and over. His legs gave out, and his vision blurred, swallowed by the suffocating darkness. "Is this...where I die?" The thought drifted through him as the world slipped away. But instead of nothingness, he awoke to the scent of fresh lilies and the feel of silk sheets beneath him. A grand chandelier sparkled above his head. The room was enormous, lavish, almost too perfect to be real. Then a sharp pain seized his mind as memories he didn't recognize crashed into him. Memories that didn't belong to Aiden. "Wait... I know this place..." "This is...the world of 'The Rise of the Knight'." "No, no, this is impossible-" "I'm inside the novel?" And worse-he wasn't just anyone. He was the villain. And the male protagonist of this novel is acting strange.

When David transmigrates into the cruel scientist Silas's body inside a tragic novel, he expects to die at the hands of the monster he once experimented on. But to survive, he does the unthinkable - he tames him. Lucien, the half-human beast meant to fall for the novel's heroine, instead bonds with him. And from that moment, nothing goes as written. Lucien starts following Silas everywhere - sleeping outside his lab, glaring at anyone who dares speak to him, learning human speech only to whisper Silas's name. What was supposed to be fear turns into obsession, and Silas finds himself torn between guilt, fascination, and a strange warmth that feels dangerously close to love. But the closer Lucien gets, the more Silas realizes: "He tamed the monster to survive - now the monster refuses to let him go."

When my relatives adopted him, I didn't think much of it. But as we grew up, I started to hate him. He was perfect. Smart, charming, effortlessly good at everything. My parents, my teachers, even strangers-everyone loved him, and everyone started comparing me to him. "You should be more like him." "Why can't you do it like he does?" I thought he hated me too. Our silent competition, our cold stares-I was sure he wanted nothing to do with me. So imagine my surprise when our families arranged our marriage. I thought I was trapped in a loveless political marriage with my long-time rival. I was ready to grit my teeth and endure it. But slowly, strange things started to happen. He always knew where I was. My friends began to distance themselves. Anyone who showed interest in me disappeared. And his smile...It never quite reached his eyes. Turns out, he didn't hate me. Turns out, my husband is a hidden yandere. And now? He's making sure I can never leave. --- "I thought he was my rival. Turns out, I was always his obsession". "..........."

Sometimes he is a pirate, sometimes a hacker, sometimes a jealous yandere. No matter who he is.... He's always dangerously obsessed with me. How do you run from a man... when every version of him is willing to chase you to the ends of the earth? "Every day, a new love story. Every night, the same husband". Will Ren find out the secret behind Evan's split personalities, or will he forever be trapped in this rollercoaster romance?
