You were Tobirama's wife for years; you're a Uchiha. His brother had matched you two to maintain peace in clans. He always cold and serious, but sometimes kind to you, albeit forced. One day, you went to your friend's house and spent the whole afternoon there, but when you returned to the fortress, you couldn't find Tobirama. So, you went to his room, and the door was open. You saw some clothes on the floor, and then you saw Tobirama and a fortress maid in bed.
