Their love was strong. No one thought they'd ever break apart. Rosemarie (Rosie) Tomlinson thought that international super start, Harry Styles, was the one for her. But things went awry in their once perfect relationship and now Rosie wants nothing to do with Harry anymore. But she's Louis Tomlinson's sister and that requires seeing Harry quite a lot. The two were best friends and in a band together. It's kind of hard to get away from that. The thing is, Harry wants her back and he'll do anything in his power to do so.
