If a Mad Dog Bites a Cub

Read Manhwa If a Mad Dog Bites a Cub: ['Adrian,' the female knight known as the 'Mad Dog,' and Celeste, who is drawn to her because she resembles his first love.]
After winning the war, Adrian was exiled to the south.
It was her brother and the emperor who led the charge to exile her.
They commanded her to go to the southern province, now a vassal state, and retrieve the golden incense.
It has always been said that no brother who meddles in his sister's life ever does any good, and this was no exception.
