Not so long ago I posted a thread looking for a forgotten novel, but unfortunately I got no feedback, so I'm trying again. The novel's setting is in Japan's Sengoku period and from what I remember, the MC grows from being a mere peasant to a lord (or something akin to a ruler). The MC is a transmigrator, but doesn't really have any cheats other than knowledge about weaponry (like a bow). The body he takes over was a weakling, often getting bullied by other boys when tending the fields, and has an older brother, a younger sister, a feeble mother and an alcoholic father that gets violent when drunk. When called to arms, the MC begins to excel and from then on his path to become a ruler begins. The MC accidentally meets the local lord's daugther (when she sprained her ankle in the forest) and they strike up a friendship which later leads to love. Later the female lead's father in war (the MC's brother also dies) and the MC takes over as lord. Does the novel ring a bell for anyone?
Doesn't seem to be on NU - There's only one novel here about a male MC transmigrating to the Sengoku era, and that one doesn't fit the description. Maybe it hasn't been posted here?
I can't find it either, the closest thing I can find is Akuyaku Reijo Ni Koi Wo Shite.. which is most likely not what your looking for so I have to agree with @aShinyVaporeon that it might not be on NovelUpdates
