Mr. Park Sunghoon, the doctor of the mental hospital in the juniors case. Sunghoon never wanted to waste his medical degree in an mental hospital and even at the beginning of his career he was not happy at all, but as time passed he became more professional and everyone in the hospital knew him.

He was a good doctor, he was calm and kind to the patients, he cared about them and did his job in the best possible way.

His life got better when a 17-year-old girl named Lily entered the hospital. She was completely crazy and always wanted to commit suicide... Lily actually suffered from post-traumatic stress disorder... A painful incident... She had been raped in the worst possible way when she was younger and she could never forget that scene and hated herself forever even though it wasn't even her fault.

At first, Sunghoon and Lily's relationship was like all other doctors and patients, but there was something that made Sunghoon care more about Lily, her stubbornness, the smiles that rarely appeared on her face, her curly hair, and her eyes, everything.

Things about Lily gradually became important to Sunghoon.. They spent more time together and Lily didn't trust any other nurse or doctor except Seunghoon, she would scream and only call Sunghoon to come and calm her down.

As time passed, almost two years passed, and it made Sunghoon really love Lily, he always took care of her, calmed her down, fed her, spoke to her kindly and gave her beautiful nicknames like "Princess" and "My girl"... Sunnghoon fell in love with Lily so much that he started writing a book about her... about the dearest person in his life.. his love for Lily.

Today was another Sunday... Sunghoon had been on leave for a few days and hadn't come to work... Lily kept crying, screaming and cursing and harassing the other nurses during those few days.

Today, after a few days, Sunghoon finally went back to work, he missed his sweet girl. And when he entered the hospital, he saw several nurses forcibly taking Lily to her room, and Lily was screaming and crying with all her heart.

Sunghoon quickly run toward her and carry her in her bad. whispered into her ear, trying to calm her her down
