This a story of a 16 years old girl, Y/n, who became the 4th wife of the Sound Hashira, just because her parents thought of her as a burden and made her get married with a person who was from the Uzui clan the famous Shinobi clan. At first she hated the idea of getting married at such an young age but later when she looked around, she saw many other girls smaller or about her age are having a peaceful happy life with their husband and even some had children too. So, she decided that it would be much better to get married than the torturing life she is leading by living with her abusive parents. No one knew about Tengen being the Sound Hashira of the Demon Slayer corp and few didn't even knew that what demon slayer corp is but Y/n knew. How? Because she herself was training secretly to join the corps as the final selection was going to be held with 2 months, the month just before hers and Tengen's marriage. But it looked like Tengen and Y/n both knew each other from before they got married. But why? Wasn't the marriage arranged?
