Hii new member here

Hey there fellow humsafers...Nope that does not sound right...
Any who..I'm new to this forum and I have got to say I'm enjoying my self.
I looked through a few post already and you guys are hilarious!

Although I don't trust gulanymore because all of her other shows...you have top admit she does have a brilliant mind..who seems to love negative characters a little too much.
I couldn't help myself,I had to give the show a try..
What definitely sealed the deal for me though was Harshad sexy Chopra!

I have also always loved the guy who plays zaki from his dmg days as yuvi!
(Zaki is my favorite, ssh...don't tell anyone) I know I'm weird right...

Anyways, the real reason I'm making this post: I'm a little confused about the characters, like who they are and how they are related?

I would really appreciate an answer..
