Disclaimer: I don't own Haruka or Michiru or Setsuna but the rest of the characters and this fic are entirely mine.

This story could be called a sequel of 'How could you?' and 'Unfaithful' which I recommend you to read but it's an independent story itself so do as you want.

Italics mean character self talk.

Unwelcome to the family Miss Kaioh!

Chapter 1: Tornado

(Ah the story takes place more or less 4 months after the end of 'Unfaithful')

A lovely spring Morning knocked on Michiru's window, she walked up full with energy, she had a ton of things to do today; Haruka was supposed to help her but she was completely knocked out; yesterday she won a huge race and she went all night partying out with the guys.

"ah, anyway she's not big help in cleaning issues" Michiru got dressed with an old dress and an apron, today she was doing the Spring Clean with Shi, so she also put a neckerchief on her head. After a few hours of hard work Michiru decided it was about time to walk up Haruka and was about to went upstairs when the door bell rang.

Michiru opened the door to find out a gorgeous blond girl on the door; she looked young 15 maybe 16 years old, her long blond hair falling to her waist; the girl wore a pair of tight jeans and a white top; she looked at her and remove her Armani sunglasses. Michiru was surprised...

"Hi, can I do something for you?"

"I'm looking for Haruka, is she home?"

"Ah ah not again please!" She's not available at the time; maybe I can give her your message"

The girl looked amused. "You have no idea how am I?"

"No"

"Tell Haruka I'm here, she'll see me." The girl passed in front of Michiru like the owner of the place, Michiru's patience was running out fast.

"How I'm supposed to announce?"

"Tell her Tazuka is here, I'll wait in the living room"

Michiru was about to scream, who on earth was this bitch on her living room? Michiru turned around to go upstairs; Haruka had a lot of explaining to do! Shishi came out of the kitchen.

"Who is it Miss?"

"No freaking idea, but keep an eye on her would you?"

"Yes Miss"

Michiru run upstairs an enter their room, she saw herself in the mirror and got even more angry she was covered in dust, not wonder the freaking girl looked at her so disparagingly, she took out the apron and uncovered her hair, then she walked to the bed to find Haruka still asleep probably having to nice dream (she was smiling) Michiru was so angry she took to glass of water from her night stand and thrown it to Haruka.

Haruka woke up surprised and a little scared. "I didn't do it!"

Michiru was tapping the floor with her foot looking rather angry. "You better not!"

"What's wrong?"

"What's wrong? Do you want to know what's wrong? There's a damn girl on my living room asking for you, a pretty girl I must add!"

"I swear, Michi I'm innocent of any charge!"

"Then why she's so sure? She's not even 16 Haruka! You promise you'll never do it again!"

"And I did! I swear! "

"She says you know her."

"What's she like? What's her name?"

"She says her name is Tazuka"

"Tazuka? Is she here?"

"So you know her then!"

"Michi put that lamp down I can explain!"

"You have three seconds!"

"Tazuka is … she's my sister!"

Michiru was surprised, Haruka had a sister? "But, you never said you had a sister!"

"Oh well, you never asked, she's supposed to be in a border school… I'm wondering what's she doing here"

"Is she really your sister Haruka?"

"Of course, don't be silly Michi." Haruka hugged Michiru.

"Ok, I'll give you the benefit of the doubt"

"Let's go downstairs to see her"

"Fine"

Michiru and Haruka went downstairs together, Tazuka was sitting at the living room, the minute she saw Haruka she climbed into her arms. " Haruka!"

"Taz! What are you doing here?"

"Aren't you happy to see your must beautiful sister? Ah why are you wet?" Michiru stand a few steps away from them, this reunion seem too intimate to butt in.

"Never mind, does your school know you're here?"

"Ah… we'll talk about it later, hey can I got some coffee please?"

Michiru looked at Tazuka. "Are you talking to me?"

"Of course who else is here? Coffee and maybe a sandwich"

"What? Does she thinks I'm the maid or what?"

"Come on don't stand there doing nothing!" Michiru blushed with anger, when was Haruka telling her 'adorable' sister she was not the freaking maid?

"Ah Taz, Michiru is not the maid , and you should say please."

"Ah sorry I thought, well she's all dusty"

"No you see Michiru is…" Michiru smiled, so now 'Taz' was going to see how wrong she was. "She's my roommate"

"What?" Michiru was so surprised she could not even talked, Haruka came closer to her and grabbed her arm

"Ah I'll take Michiru for just a moment we'll go fetch you some coffee, I'll be right back"

Haruka and Michiru stepped into the library Michiru was now really really pissed.

"Roomate!"

"Don't shout, I… Tazuka knows nothing about us… ah she doesn't know I'm… we're…"

"Lesbians! The word is lesbians!"

"Shh, please Michi I'll tell her"

"Our wedding is in less than 2 months and you have not told your sister…. Oh I feel so special now Tenoh!"

"No please, don't get upset, I swear I'm going to tell her give me just a few days…"

"A few days? Tell her today!"

"Michi, she's just a girl do you have any idea how much emotional trauma I could cause her?"

"Her? What about me? I'm supposed to act as your freaking roommate?"

"Please, just a few days"

"Fine, you have till Thursday, if you don't do it then I will, ok?"

"Ok, thanks Michi"

"I can believe this Haruka I …. Ooh I'll go make the freaking coffee…."

(Poor Michi she's always into troubles doesn't she? Let's see if Tazuka becomes a nice sister… review if you want some more!)
