Although its little bit boring as i prefer romantic plot more, i still managed to complete it as it has an interesting plot with great acting by all characters....

Every character did justice to their role... Main leads to side ones... I read many comments about FL being toxic & villainous... Well its totally justified how she turned out after having such a terrible childhood... She was brought up that way... so her behaviour was justified... So as Ml's autistic brother's... obviously its difficult for Ml to manage an autistic patient along with the childhood trauma... Its not easy... But his bro was equally supporting & caring for ML in his own way... He understood ML difficulties as well as his moods over situations better than anyone else... He tried to cooperate as much as he could in his condition. In the end, he actually saved everyone from evil. About Ml, he patiently handled Fl & his bro's tantrums while coping from his own traumatic past. He was one of those kid who had to become adult despite his age cause of certain situations. I really feed bad & sorry for him.

About side characters, Sang In & Jae soo were really great friends for fl & ml respectively... They gave their unconditional support & love to them... Joo ri's mom was best among all moms in the show. She really cared about everybody's appetite & diet. No one would be hungry around her... Hospital's staff & patients were like a big joint family...
Overall the whole drama based on everyone's own psychological trauma & their way to overcome it... It was encouraging...
