Go Ahead and Exile Me as the Useless Sister, but Don't Come Crying to Me Later!

Racine, a duke's daughter, was mistreated by her family as a "failure" who could only cast simple plant-sprouting magic. When her fiancé, the Crown Prince, and her own younger sister collude to break her engagement and exile her, Racine happily accepts her freedom and runs away to the frontier!

Settling into the Margrave's domain, her peaceful, stress-free new life causes her true latent talent to awaken. Combining her magical green thumb with her deep botanical knowledge, she creates revolutionary plant products that become massive hits across the realm. As Racine becomes an indispensable hero in her new home, the former fiancé and family back in the capital realize the catastrophic mistake they made when their own lands fall apart without her.
