give me some mangas where the uke is older and independent, not poor or rely on the seme
Also if u know mangas that the seme is bad ( not a criminal but using the uke/mistreat him) and the uke doesn't really like him but forcing himself to be with the seme because he needs him for his safety/ he is being blackmailed
