i forgot the name of what i was reading recently and can find it anywhere,
its guy who reincarnated into a young boy in an magical world and the magic has colours/elements?
he was a teacher in his life on earth and trained assassins/spies or something like that he was already old.
he was born from a mistres(died because of child birth) and his father does not care about him because he already has a heir and he lives in house with only the maids and a cook i believe
thats al i can remember
