Well friendship is the 1st step towards the further relation you might be his/her good fren for life time and other relation can be formed as well but this is the way of relation that determines all
Well as far as Ive known or experienced.Its really hard for a guy n a gal to remain each others best frens 4 along time.There r two cases.One is if u r alresdy engaged thn there's no prblem.But if u r not then the love story begins here. I guess anyone might start feelin 4 the other person lik Ive already felt for ma best fren.
