Bungou no Hanayome

Tsuzuri, the daughter of the Kitakoji family, was forced to live a life worse than that of a servant as the daughter of a concubine, but she had been betrothed to Seiji, the second son of the prestigious Todo family. However, the marriage was unilaterally broken off on false grounds. Years later, Seiji reappears before the heartbroken Tsuzuri, having lost everything, as a rising writer named Mibu Tosei. He asks her to marry him again. Tsuzuri is suspicious of Seiji, who seems like a completely different person, but he harbors a shocking secret.
