Taeyeon lived a painful life. Neglected by her parents because of her brother Heechul. For 15 years, she's tried so hard to please her family, especially her father. But a tragedy has changed everything. Heechul, the only person that showed so much love and care for her, died. As she tried to move on, she meets Chanyeol in middle of the journey. And just when she's starting to fall for Chanyeol, Baekhyun comes back, making her torn between the two of them. But what if something's wrong with the both of them? Baekhyun is a fun to be with, yes, but he's too secretive. He's hiding something, and that part is somewhere Taeyeon can't touch. Chanyeol has his fair share of secrets, too. But he's less shady compared to Baekhyun. Will she discover their secrets?
