Hawar in the Winter Garden

Princess Canola was pushed into a fight for the throne and had an arranged marriage far away from the kingdom. She fell in love with her fiancé she saw for the first time! However, the people of Tripole, where she will marry, treat her as a stranger and ignore her, notifying her that she cannot marry until she passes three tests. Even her fiancé is cold to her... but she can't back down. She has already named her grandson and granddaughter. She'll get through that exam quickly!
