Silent Oath [Lee Sangwon FF] ☑️

Book 1 - Silent Oath

He swore never to get personal. She swore never to need saving. But some oaths are meant to be broken.

Lee Sangwon lives by rules. As an ex-military strategist and head of a private security firm, discipline and distance keep him sharp. No attachments. No distractions. Protect the client-then walk away.

Yoo Hyejung has spent her whole life behind the gates of her family's estate. After a string of mysterious break-ins, she hires Sangwon to keep her safe. But the deeper he digs, the clearer it becomes: the threats aren't random. Someone wants to unravel her family's legacy-and her name is the key.

What begins as protection turns into something far more dangerous. For every night Sangwon guards her, the walls he built around himself begin to crack. And Hyejung, who vowed to stand alone, finds herself leaning on a man who might just risk everything to shield her.

But in a world of syndicates, betrayal, and blood oaths, loyalty has a price.

Will Sangwon keep his silent vow of detachment... or break it for her?
