Eun Amina was the model student, the perfect child, until she discovered a secret her parents had hidden from her since birth. Torn between loyalty and self-dignity, Amina set out on her own at the age of seventeen and strived to create her own path in life. Six years later, her goal of finishing medical school is in sight but her emotions are destined to get in the way when she meets Taeyang. Dong Youngbae a.k.a. Taeyang suffers a concert accident that requires medical care for a couple of weeks until completely healed. Due to the overwhelming security needs of this K-pop idol star, arrangements are made for in-home care. Personally chosen for Taeyang, Amina is not the type of care-taker that he expects. She is unlike any of the girls he's met over the years - hard to read, guarded, and.. sad? He can't help but feel that she's carrying a burden inside her. Working together in close quarters, Amina and Taeyang spark a connection that both of them try hard to deny. While she is working on healing him on the outside, he is working on healing her from the inside. Every day he learns more about her and pieces together a clearer picture of who she really is. But will he still have feelings for her once he discovers her secret?
