The drama has three pairing, Poodit & Saiparn, Napat & Nida, Narin & Porkeaw.
Would you watch and leave someone you love to go crazy and depressed to the point they hurt themself and others? Wouldn't you try do something? Or find a way to make sure they overcome it? Mental health is a serious matter, if no one wants and tries to help the patient to get better, only themselves won't do. They need support and encouragement in order to get better.
Nida's mental state isn't that great because she got hurt, we know. But everyone isn't just going to leave her and let her continue to hurt herself. They all want her to get better....Even though we all hating her princess syndrome, she's unble to cope with her own sister stealing her lover, a sister whom she loves and was always good to. She's afraid she'll lose more people that she loves, everyone will love Saiparn and not lover her anyone....especially lose her father to Saiparn that he'll love Saiparn more. Nida grew up with so much love and attention, being the youngest daughter and the beloved daughter. Especially her father.
Saiparn, Poodit could have gave her some attention.. He did but he was worried about Nida too, someone he was in love with. Everyone is worried about Saiparn too but they trusted Poodit to take care of her. He doesn't know what to do, but he tried to protect her from his mother and Sirikanya.
