Her master save her during the war, and teach her martial arts and medicine. Her master, as she described, "The most handsome devil man in the continent", is a well known physician across the continent who was so proud of his prodigy genius discipline in medicines- who later turns out to be so lazy to continue his legacy.
She save a man from a slave market when shr was 10 years old. As she predicted, he turns out to be a heartbreaker few years later. She spend her youth chasing away her brother's lover who can't stop knocking on their door. Apart from breaking young maiden's heart, poisoning people is his other specialty.
When she was 15 years old, she saved a man dying at the entrance of their Sacred Forest who turns out to be an assasin. With no directions to go, the man decides to follow them on their adventure to find her master (her mission is to pester and drive her master crazy to death). Watch how she turns the ice block into a warm, Prince charming as she drive him crazy and seduced him along the way. The once obsessed assasin who only interested in killing people, under the guidance of her heartbeaker brother, slowly turns into a docile housewife.
