here are my suggestions
1) for armaan......for once in yourlife act like a sensible man...get off the counch and try fighting for gm......make your parents proud and ofcourse try asking forgiveness for past blunders from jassi
2)for purab......well you are not escort service so don't act like one....let jassi go even she is wrong and concentrate on your life .
3)for jassi...get an ounce of brains and an ounce of backbone...that is all you need for your makeover now or all this beauty thing is gonna go waste
4)tony and diya...decide on one storyline and stick to it .....your story seems to immitate ekta stories(without her class and strengths)
5)nandini.....you can't change a person who does not want to change or realises her blunders...so leave jassi alone
i can go on and on but for now this should do
