It's a great naruto fanfic with a lot of potential since this era is rarely used, and you can even experiment with it a little bit. Now I have a recommendation for the Love Interest.Since he's a Senju and he is gonna be the Third Hokage, I recommend Tsunade so for "bloodline purity" and so they can keep the power of the Hokage to themselves(The Senju) since no one know he is a senju, and with that, the child could be the 4th or 5th Hokage without the people knowing it's another pure blooded senju. , An Uzumaki for tightening the alliance between Uzio and Konoha. It will definitely provide a strong heir whether be it chakra, kenjutsu, vitality, fuinjutsu, or ninjutsu. An Uchiha to strengthen the loyalty of the Uchiha to konoha, and providing a strong heir with senju vitality, uchiha sharingan, and kenjutsu. Last Option is a leading clan from other villages(least likely) for an alliance.
