I've always hated Harem and Ecchi along with the typical Weak Ukes in manga.
For those who hate those tropes this list contains:
Smart Male Leads
♧Strong Male Leads
♤Strong Ukes
♧Strong Semes
♤Healthy Relationships
♧No Ecchi
♤No Harem
♧No Oppais
◇◇◇◇◇◇◇◇◇《Enjoy》 ~♡♡♡♡♡♡♡♡♡
PS: I'll try to give a review for ever manga that I possibly can on this list. Some of them may have only plot summaries as of now.
