The Taming

As soon as he came of age, Michelle Arnold, the youngest son of a southern noble family, was sent north—sold off, almost—to marry. His betrothed: the cold master of the North, Ian Shelleg. But when Michelle arrived, it was not the promised castle that awaited him, but a small, secluded mansion... “For the next month, I will serve you in my master’s stead. My name is Ain.” There, instead of Ian Shelleg, stood his servant, Ain, waiting for Michelle. They told him it was to help the southern noble adjust to the unfamiliar North— to teach him its manners and customs before the wedding. With his black hair, blue eyes, and cool expression, Ain, who so resembled his master, asked in that same chilling voice: “Did I not tell you? I will teach you how to win my master’s heart… even in a single night.” And so began the training—day and night— to capture the heart of Ian Shelleg. A servant who mirrors his master— was it mere coincidence… or something deliberately planned?

All Seo Jae-eon had to his name was his body, but even he once had a first love as warm as spring. That love was Yoo In-ha—an alpha notorious for changing partners almost daily—whom Jae-eon secretly adored. But between them, their only connection was convenience-store clerk and customer. To make matters worse, Jae-eon wasn’t even an omega who could catch an alpha’s eye—just an ordinary, unremarkable beta. Even so, Jae-eon told himself it was enough just to watch from afar. Yet one day, like a bolt of lightning, a chance appeared before him. Two pills—capable of making a beta pass as an omega. Even if the relationship was built only on lies, if it let him touch Yoo In-ha just once, Jae-eon’s hopeless love began to burn with the false scent of an omega. **Original Novel:** Volumes: [RIDI](https://ridibooks.com/books/3302002799), [MrBlue](https://www.mrblue.com/novel/E000092796), [Bookcube](https://www.bookcube.com/detail.asp?series_num=922018133) Chapters: [Bomtoon](https://www.bomtoon.com/detail/tenbook030), [MrBlue](https://www.mrblue.com/novel/E000117305) [Original Webtoon](https://ridibooks.com/books/5163001357) [Official PV](https://www.youtube.com/watch?v=3ovW3ZSf7UQ)
