Forgot the name of a manga

[leemccaff]

Hey, I'm looking for this manga where these two rivals in school can't stand each other, their grandparents make them live together and force them to marry but they hide it in school, i think they are both really smart. Can't remember much else, any help finding it would be appreciated.

Not exactly rivals in school, but Raise wa Tanin ga Ii has a somewhat similar set-up to what you described. Engaged to the Unidentified is another series with a grandparent-arranged marriage, though the couple gets along fine. Probably not it, but Nisekoi is there.

Thanks for the suggestions, I'll keep looking.
