Hi all. I'm looking for manga with an arranged marriage between the two MC and a really slow romance. A perfect example is Tale of Felluah

Ideally what I'm looking for is:
-A purely pragmatic relationship/marriage in the beginning
-Preferably no realization of feelings within the first 15 chapters or 3 volumes. The longer it takes to develop, the better
-The two characters are resistant to each other's charms (in the beginning at least, for quite awhile).
-No smut/hentai please

Thanks for the help =)

I only know Takane to Hana, it's quite a new manga but hasn't updated since the group is busy with RL.
It's quite good, have a try

Hmm the only one I can think of is Nigeru wa Haji da ga Yaku ni Tatsu, but it's not arranged marriage more like marriage of convenience, and only can be read at otakumole

DONDAKEE!!

Try:
Hadashi de Bara o Fume
Goong
Habaegui Sinbu
Hapi Mari - this one does have smut

You might also like Zettai Heiwa Daisakusen or Kuro Hakushaku wa Hoshi o Mederu - the realization comes earlier than you wanted, but it does take a while to admit.

Otoyomegatari - they get along very amiably, but don't develop romantic feelings until a bit later (though it's hard to tell how the male lead feels).

Zettai Heiwa Daisakusen - I remember it takes a long time for the female lead to fall in love, but there's a lot of charm-tension floating around in the beginning, so it might not be to your liking.

Thank you for the suggestions, everyone =)

Bread & Butter would fit, I think. It's more of an impulsive marriage proposal, but the romance moves slow and it's quite nice.
