bring me to upto speed on KZK

hello,

i live in new york. i was an avid watcher of Kasauti zindagi ki and left way back. i left when aparna and komolika come back. prerna has teamed with aprana but in reality she is just pretending just to get even with apurna. anurag has married sam. i would greatly greatly update if you can just give me the nuts and bolts of the episode since then till date. i just happen to watch online ther recent episode of kzk and was tempted to start watching but i am at my wits end because i cannot make sense obvioulsy i have missed out a lot. just bring me upto speed please. thank you in advance
