its very clear ..and nw there is no mystery..
abhi was not d person who was writtin these letters...
The story is ...it was one deewana ov shikha..who was writting lettrers 2 her nd without revealing his identity..without any name he was sending letters..shikha was also attracted by him with some words written on papers..so they were abt 2 meet but b4 tht tregedy took place n tht guy met with an accident..
nw abhi was his friend nd on d deathbed tht frnd took promise from abhi..tht he l meet shikha on his place ..
nw on u can guess..
agree?
