Two years later, Megan's life is nothing like she imagined. After losing her job, the person she loved, and everything she once thought she had figured out, Megan has spent the last two years trying to start over. Now twenty-six, she's ready to leave the past behind and finally rebuild her life. Or at least, that's what she thinks. When Megan gets the opportunity to work at a prestigious new dance academy, she sees it as the fresh start she's been desperately searching for. She knows nothing about the people behind the academy, and she's determined to focus on dance and forget everything that happened before. Until she walks through those doors. Because the academy belongs to someone Megan never expected to see again. Yoonchae. The girl she was forced to leave behind. The girl she never stopped loving. And now, Yoonchae isn't the same person Megan remembers. She's grown into a confident, successful woman who built an entire future without her. Megan has to face the consequences of everything she did two years ago while working alongside the one person who can still make her forget how badly they once hurt each other. Old feelings return. Old wounds reopen. Secrets from the past begin to surface. And this time, they can't simply run away from each other. Because sometimes... the person you spent years trying to forget is the one person you were never meant to lose.

Megan and Sophia have been best friends since they were three years old, the kind of best friends who tell each other everything. So when Megan suddenly starts noticing Sophia's younger sister differently, it becomes impossible to hide. Jeong Yoonchae was always just there - sweet, pretty, and completely off-limits. But the closer Megan gets to her, the harder it is to remember the one rule she should never break: "Don't fall for your best friend's sibling." Unfortunately for Megan, she already has.

Megan is pure, blinding light, a charismatic dancer who doesn't even know the darkness she casts. Yoonchae is the shadow. She has been secretly, painfully in love with Megan since childhood, carrying the weight of that unsaid truth like a growing scar. She watches, helpless and alone, as her best friend, her whole world, drifts away, oblivious to the breaking heart she leaves behind.
