Have you read http://www.mangago.me/read-manga/the_legendary_moonlight_sculptor/?o6Dx ? It's pretty good (and no harem as far as i remember (๑•ㅂ•)و✧ )
WOAHHH THANK YOU EVERYONE (≧∀≦)
Like the ones where the main lead is super fucking powerful? Something like Kill the Hero or Solo Leveling. It would be nice if there were no harems too :D. Thank youuu
