One lie leads to a spiral of secrets... Yuri was always seen as the perfect daughter, perfect sister, perfect girlfriend; she was perfect in every way... but that's only the surface. In reality, she isn't as perfect as everyone thinks. Nari is three years younger than her sister. She and Yuri had always been close; they knew everything about one another, at least that's what Nari thought. Yet when twenty-one year old Yuri was found dead with a suicide note left behind, she can't seem to figure out why her sister would take her own life. Yuri's boyfriend finds it strange too and they are both determined to find out what happened. Jungkook was Yuri's first love, at least that was what she told him, but in fact there was someone else before him. Determined to uncover what Yuri is hiding and find out what really happened, both him and Nari will begin to discover Yuri's secrets and expose the truth. In the midst of revealing Yuri's lies, Jungkook and Nari find love and realise that they don't know Yuri as well as they thought they did.
