I hate this mean male lead trope too, especially because in most cases they do little to redeem themselves.

http://www.mangago.zone/read-manga/kare_wa_tomodachi/ (both the male lead and female lead are too good for their own good, like seriously their kindess gets taken advantage of, got two annoying people there though)
http://www.mangago.zone/read-manga/eden_no_hana/ (my favorite male lead of all time probably, but sadly female lead gets harassed by almost everyone)

http://www.mangago.zone/read-manga/get_love/ (she ends up with the nice guy, check out the rest of the authors work.. All her male lead tend to be not annoying)

http://www.mangago.zone/read-manga/tonari_no_atashi/ (Female lead has to go through some annoying stuff, but she ends up with the good guy who shows up some chapters into the manga, not the first guy who appears who she is in love with first)
http://www.mangago.zone/read-manga/hirunaka_no_ryuusei/ (ends up with the good guy, not the jerk. I think it had one annoying girl there though)
http://www.mangago.zone/read-manga/parfait_tic/ (ends up with the good guy, not the jerk)
http://www.mangago.zone/read-manga/marmalade_boy/ (Male lead is kind of the kindest guy, so girls always fall for him ~.~ So yeah annoying jealousy drama occurs)
