Searching for a romance story with a couple like in the title. But i want the popular one to be the proactive in the relationship (not the kind of manga where the normal one tries everything to get closer to the popular one, i severely dislike that kinda plot).
Example: Sukitte ii nayo is a good example for what i want
No Yaoi and no Harem please.

Last Game
Horimiya
Kurenai Ouji

________________

Seconding Last game and horimiya

3D Kanojo- Popular girl x otaku
Dear Tear-Popular boy x normal girl
Hibi Chouchou-Somehow the popular girl act first.
Kimi ni Todoke-I actually forgotten who confessed first lol
L-DK-Popular guy x normal girl
Kyou, Koi o Hajimemasu
Kirai- Playboy x normal girl?
Gakuen Ouji-A reverse harem tho (incase you like the plot )
Kimi wa Midara na Boku no Joou- The female act first

Iris Zero, maybe

Renai Boukun - parody of a harem. The only one who likes the MC is the popular one.
Witchcraft Works

Every manga that I wanted to suggest has already been suggested /:

Haru to Natsu
Yasashii Sekai no Tsukurikata student-teacher relationship, still in progress because of dense guy

B Gata H Kei
