Flower of Love
In the novel, there is a flower called the flower of love (情花) which although beautiful, has hidden thorns. The thorns are very poisonous and it could be fatal if pricked by even one of them. Upon any thoughts of love, the victim would be hurt by the poison. There is only one antidote to the poison of this flower, the passion pill, which is a tiny square-shaped tablet.
พิษดอกรัก กำเริบทุกครั้งที่คุณไม่อยู่เคียงข้าง ทุกครั้งที่ฉันคิดถึงคุณ
