here's my richxpoor list http://www.mangago.me/home/mangalist/68437/ i have marked the rich uke there. also, i prefer recommending finished mangas so you will find a lot of finished stories there
Kanemochi kun to binbou kun
Looking for a yaoi manga in which the uke is super rich and seme has a simple life. Much better if its completed. Thank you!
