Re: husband interested in wife’s sister

@Adorlove

Husband is interested in wife’s sister and whenever he see her he gets that flirty smile on face. The family of his wife hates him for this and even the wife’s sister.
What opinion and advise do you have for this girl?
What should she do?

just that *dil hai ke manta nahi *
