Here's Chapter 2 rewrite, I practically correct all the grammatic mistakes I saw.

So...here goes

Chapter 2: Nice going...

Okay... Seto Kaiba thought as he picked up the phone, just this once...

"Hello?" said Kaiba
"yes Kaiba?" said Isis
"I was wondering if you know how to cook?"
"Why of course, I do it for Marik everyday..."
"So can you like come over... wait... where are you?"
"Sorry I can't, I'm in Egypt"

"Hello?" said Kaiba
"Oh, hey Kaiba, what do you want?"
"Tea, do you... um... like know hew to... um... cook?"
"Yes? Why... you need a cook?"
"Can you teach me?"
"No!" then Tea hungs up right away without saying bye (this is very unusual for the friendship-girl). That is because she was right in a conversation with Yami.

"Hello?" Kaiba called someone again.
"Yes? What do you what, genius not really?"
"Look Rebecca, just because you helped me on my computers for ONCE, doesn't prove that you are smarter than me"
"sure, I guess that means you don't need my help."
"I just want to ask you if you know how to cook!"
"No, and bye", Rebecca hung up right away, not wanting to talk to the cold CEO

Okay, last one... I can't believe myself! "Hello?"
"Hey moneybags what do you want!"
freaken mutt!
"Look Wheeler, this have nothing to do with you, okay? So just hand over the phone to your sister."
"Why should I? What do you want from her? Unless... YOU LIKE HER!" Joey screamed at the phone
"I just want to ask her something and I don't like her!"
"Fine"
"Hello?" Serenity said softly
"Hey do you know how to cook?"
"Sure of course!" Serenity said wondering why," I cook for Joey all the time!"
I thought Wheeler said he can take care for himself, ha! Well... here goes, I got nothing to lose but my reputation, which means a lot! "doyouthinkyoucanteachmehowtocook?." Kaiba said EXTREMELY fast
"what? sorry, I didn't hear you, did you say something about cooking?"
"Yes... I said can you teach me how to cook?"
"Why sure..." Serenity answered nicely
"good, you better not to tell this to anyone, especially your pathetic brother! Come to my house ASAP!" Kaiba demanded, then he hung up. Serenity hung up too.

(Serenity's POV)
O.M.G. Kaiba just asked me to go to his house

That's so unbelievable. :)

(Normal POV)
Serenity had a crush on Kaiba since Battle City:

She couldn't forget the way Kaiba acted when he was dueling, she couldn't forget the way he drawn his cards, she couldn't forget the way he acted, the way he looked! It's so handsome! Serenity blushed as she thought about it.

She picked out her best outfits, and got ready to go.

(Kaiba's POV)
oh great... look what you've done, Kaiba...

Nice going, Seto... you just invited the Wheeler girl over... good job!
