guyz not convincing...

well its in one of the episodes the other day when khushi discloses to anjali about her broken engagement and asks her not to disclose about it to anyone as everyone will be upset and stuff... what i fail to understand is she only takes aakash and payal's name, why not la and arnav afterall they were also be supposed to be getting engaged right?? i guess not only sanaya but khushi kumari gupta knows as well about the script and story of ipkknd haaa heee
