Harry and Rosie break up when Harry cheats on her whilst drunk. Both are still not over the breakup, and they still love each other, even though they try to block the thoughts out.
In a weird coincidence, Rosie and Eleanor start work at the same shop, Abercombie And Fitch. Rosie, who doesn't know about Eleanor and Louis, becomes friends with Eleanor, and meets Harry again.
Will they fix their mistakes and realise their love for each other, or will Rosie decide she doesn't want anything to do with Harry.
