After centuries of being enemies, Uchiha and senju clans decided to sign a peace treaty and arrange a marriage between the second son of the head of Senju clan and the second daughter of the head of Uchiha clan as a symbol of peace between the two clans.
They didn't want any other death so this happened.
Things went to fast and you, the second daughter of the head of Uchiha clan are getting married to Tobirama Senju, The second son of the head of senju clan.
Now you are wearing a white Uchikake and Tobirama is wearing a black montsuiki the clothes of bride and groom.
Others were being happy, some of them not really happy about this either. You and Tobirama were sitting next to each other with your siblings and your family next to you. Tobirama looked serious and cold as his usual self.
A few people were playing music and some women were dancing to the music.
