http://www.mangago.zone/read-manga/hana_ni_arashi/ this ones different, female lead is kinda cool, and the male lead is really strange and eccentric, it makes him cool. Not a typical read :D
these ones aren't so similar to the one you mentioned plot wise or relationship dynamic they're just all ones I really enjoyed that don't have a horrible heroine or evil male. I loved the one you mentioned too.
http://www.mangago.zone/read-manga/kinkyori_renai/ heroine is kinda evil but its her charm :D sorta a bratt but she's clearly meant to be
http://www.mangago.zone/read-manga/mahou_tsukai_no_yome/ different and awesome
LOVELY COMPLEX!
the characters are all hilarious and super likeable
the couple is a tall girl and short boy :)
Can i anyone help me to find a manga that doesn't have annoying girl.. and the couple doesn't make you all feel hateful, not yaoi... for example like keishichou tokuhanka 007.. thx (=・ω・=)
