[WWTBC] College FMC and MMC are from enemy mafias. FMC is sheltered and the MMC helps her see the world despite the family fueds. (MC are named Ember and Ash)

I saw this on kindle a few weeks ago back but the two main characters go to the same college and the FMC has lived a sheltered life and the MMC helps her out of that, despite their fueding families. I think their families belong to enemy mafias. If I remember correctly the main characters names were Ember and Ash
