It seems that in addition to being robotic, the MC is asexual, not that there are any relevant characters for romantic interest for this eunuch MC.
I don't know but I find it difficult to see Tsunade taking the MC to the series, the difference in age and experiences is a very important factor. I know she only had Dan as her boyfriend and fiancé but it's still very strange.
Rk6T:Tsunade seems like the perfect one for him atm. They already have started to bond during the war and after. It wouldn't seem forced of the got together. As long as author takes his time to develop their relationship it will be fine.
