Tristan and Isabella were not like typical siblings. They rarely fought. The twins could even put up living in the same house together while their parents moved to Italy. When Tristan invites Derek Casey to be their new housemate, all the memories and feelings Isabella packed away in boxes in her heart and mind are suddenly beginning to burst open again. Derek and Isabella both go on with living together, thinking the same things, but acting totally opposite. Derek keeps thinking: what she doesn't know won't hurt her. While Isabella on the other hand thinks: it hurts him more than it hurts me. Can these two hopefuls remember to look before they leap, or do they plummet from the sky, falling full force?
