You are an Uchiha. Who was forced to marry the second leader Tobirama Senju. By a peace agreement between the clans. Tobirama obviously was not in agreement with all of this because he hated the Uchiha and now he would have to marry an Uchiha. You were transferred to the Senju fortress to stay. Hashirama and Tobirama are brothers but with different personalities.

Hashirama: welcome to the Senju fortress.

While Tobirama looked at you with disdain.
