http://www.mangago.zone/read-manga/papa_s_assasin_ryuunosuke_wa_tonde_yuku/
http://www.mangago.zone/read-manga/koisuru_boukun/

I've already read both(￣∇￣") they are really fun....I might reread them... thanks (≧∀≦)

Well another one: http://www.mangago.zone/read-manga/complex_manda_ringo/ (Don't get discouraged by the artstyle)

http://www.mangago.zone/read-manga/hana_to_ikkun/ (It is a series)

And my personal hidden gem: The rules/Hydra series by Miyamoto Kano. It is a long series with interlinked coupled and a lot of sequels. It has a bad rating but I love it because of the topics involved - prostitution, cheating)
