Kang Jaehyun

Seo Yuna had spent three years dreaming about becoming an idol. Now, at twenty, she was the main vocalist of LUMINA, one of the industry's fastest-rising girl groups. She was known for her sweet personality, puppy-like eyes, and habit of getting embarrassed over absolutely everything. Kang Jaehyun, twenty-one, was the leader and main dancer of VANTA, a hugely popular boy group. Calm, observant, and effortlessly confident, he rarely let anything get to him. His dry humor often left his members laughing while he barely changed expression. Their groups had crossed paths countless times at music shows, award ceremonies, and year-end festivals, but they had never been close. That changed when their companies announced a special collaboration stage. For the next month, Yuna and Jaehyun would be rehearsing together almost every day. And neither of them expected how quickly the cameras would start catching the little things between them.
