Whose star will shine the brightest?

As a talented singer-guitarist with a dream, Kim Saera longs for something bigger. When a massive online audition for the new reality TV show, The Brightest Star of All, is launched, she decided to go for it and try her luck. With so many other talented competitors from all over the world, she figures she probably won't make the cut. But still, it was a great start and a good way to prove to her parents that she's ready for a brighter spotlight.

To Saera's complete shock, she passes her audition. The world-known SM Entertainment has selected her to represent the company in the competition. Next thing she knows, she's dealing with wardrobe fittings, cameras, reporters, vocal coaches, and intensive training facilitated by SM superstars EXO. What else could she have wished for?

But soon, she realises her close friendship with her idols poses greater danger to her than she'd ever imagined. At this point, love is something she needs to avoid at all cost - but who can resist the charm of the EXOs?
