Hey!! You all were standing onthe railway tracks knowing that the train was rushing towards you and yet now you complain that the train hit you!!!!!!!!!😆 We all saw it coming folks.!!!
Armaan did change overnight.
Armaan changed AFTER he heard Jassi was getting married.That's when his world really turned upside down.
Armaan never loved anyone other than himself.He couldn't accept that he could have feelings for anyone else especially someone like Jassi.So what better way to purge her out of his system than to make himself beleive he hated her!!!! He had taken Jassi for granted & being the vain person that he is,he never even thought that Jassi too can have someone in her life who loves her.That was the shock which woke him up.He is still trying to come to terms with the fact that a girl,any girl can have so much hold on him.Fight her,beleive me,he will. Here,a reverse pschycology is at play.That's where the saying comes from: you cut your nose to spite your face!!
That's what this story has been about all along.Armaan,the biggest flirt around ,never beleived in love,actually helplessly in love,BIG TIME.
