Kang Seulgi isn't just an exceptional idol, she's one of a kind--she's never fallen in love all her life and she's already 21 years old! Growing up and training with beautiful men all around her hasn't changed her disposition whatsoever. But what will happen when a certain member from EXO takes an interest towards her? Seulgi's now-famous childhood friend wants to reconnect, and the winner from SMTM3 wants something more than concealed friendship?

Seulgi has always viewed love with rose-tinted glasses, but she's going to figure out soon enough that in the world of idols, love will never be what she expects it to be and she'll never see it come and go until it's too late--or if the public finds out first.
