Charlotte Austin's life was built on a foundation of success: a thriving career, a devoted girlfriend, and a grandmother who was her only remaining family - until she wasn't. When her grandmother's health fades, a forgotten promise resurfaces - one made long before Charlotte could grasp the weight of true commitment. A vow that binds her to the last person Charlotte would ever trust - and the very person she's spent her life avoiding. Engfa Waraha. The self-centered player from Charlotte's past. The tormentor who turned Charlotte's life into a battleground. The feeling was mutual. Charlotte saw Engfa as a superficial ideal - the last person who could ever understand the meaning of loyalty - and Engfa saw Charlotte as nothing more than the fake girl, the embodiment of everything she despised. But fate, it seems, has a way of turning everything upside down. In a single, fateful moment, everything they thought they knew about themselves and their futures shatters. Now bound by a promise neither of them fully understands, they're caught in an unavoidable web of secrets, betrayal, and a connection they can't escape. It all begins with a bitter vow - and neither of them could have anticipated where it would lead. ***** 🚫⚠️This story contains strong language, explicit sexual content, slow-burn romance, and heavy angst.
