The Dragon’s Soulmate is a Mushroom Princess

As a result of the divine spirits' protection, Agnes has an unusual and often embarrassing power: whenever she experiences strong emotions, she makes mushrooms sprout on people! One day, her royal fiancé, who claims to have dragon blood, breaks off his engagement to Agnes, claiming to have found his true soulmate. Her reputation tarnished, Agnes vows to return to commoner life when she's unexpectedly summoned to a ball by her ex-fiancé's cousin: a prince who is far from horrified by her mushrooming him.

Agnes is an unusual young woman with peach-blossom hair and the fairy-given ability to make mushrooms sprout willy-nilly. Fortunately, she's now in a relationship with a handsome dragon prince who's absolutely obsessed with her mushrooms! Unfortunately, Agnes is still trying to get over the trauma of her last relationship, and it'll take a lot of spoiling from Claude to help her! This is the story of how, through a series of unlikely events, Agnes has found her mushroom-loving prince charming.

Agnes has never thought much of herself or her troublesome ability to commune with divine spirits, which has plagued her life with randomly sprouting mushrooms. But now that Prince Claude has assured her of his love and acceptance, she's started to regain some of the confidence and self-esteem that she lost during her long, painful engagement to her ex-fiancé.

Agnes and Claude have been preparing for their wedding since returning from the Kingdom of Oreille when they receive troubling news about the Hole in the Wall growing bigger while they were away. Agnes learns this hole is where monsters come from and has been maintained by the Oreillian and Visage royal families for generations. Having learned of the ancient duty of the dragon-blooded Visage Royals, Agnes begins to wonder about her own role as a descendant of Oreillian royalty and what she can do to help.
