Prologue
One couldn't count Jun Kurumi as the friendliest person they ever met- but she had a smile that made it impossible to hate her. She would always assist when she was asked but she was quiet and always kept to herself; Jun Kurumi always turned down karaoke events, birthday parties, shopping sprees and friendly lunch time. It wasn't an assumption, it was a fact. Jun Kurumi made certain everyone knew this fact blatantly at the end of her first year of Ouran High School- all new students would be introduced to the rules surrounding Jun Kurumi and it never went any further.
At least… That was until Jun Kurumi met Fujioka Haruhi.
The host had come with a storm of apathetic normalcy and enchanting poverty- this did not sway Jun Kurumi's unfriendly attitude. Fujioka Haruhi was a disturbance in her class room and her ranking slipped from First to Second rather quickly. Never had Jun Kurumi felt such a rage as she did towards the scholarship student. At times it came off snobbish when she wouldn't scream over Fujioka's smiles, when she couldn't stand being seated next to the host and made it obvious when she moved.
'Just like her step sister,' people would note, Jun Kurumi would flinch before glaring at them forebodingly with her dark eyes.
Kurumi, surprisingly, was never such a cold hearted person. Actually, before all this- Kurumi was rather well liked
Ayonakoji wasn't that terrible a person, high-nosed indeed, but she was rather serene and graceful. Her Japanese and obviously German heritage left Kurumi jealous at her sister's beautiful brunette hair upon her placid expression. A perfect lady which Kurumi had aspired to be, but her conventional look made her appear too hollow with the expression and so she settled with an upset expression which seemed destined to give her wrinkles by thirty.
Ayonakoji's banning from the Host Club had shook Kurumi's world as it surrounded one person- Fujioka Haruhi. Kurumi wouldn't hear the end of her step-sister's agonizing threats upon Fujioka while her heart brokenness was showing plainly towards the world for the first time. It disappeared as quickly as it appeared but Kurumi would never forget the pained expression Ayonakoji held when she walked out of the room dripping with tea and crying on her arms.
This was when Jun Kurumi began to hate Suoh Tamaki.
They were shallow liars. Just moments before they would whisper how much they loved her sister until she proved to upset them and they toss her out like a dog after collecting their money; Kurumi was so disgusted she confronted the first one she saw. Otohori Kyouya. She struck out at him and slapped him in the fit of rage she possessed before spitting on his suit and running back to comfort her sister. This went down in Kurumi's mind as the grandest mistake in her entire teenaged life as the next day she was approached by someone in her class asking her if she had a sister named 'Ayonakoji'. This had been quiet a secret from the students and she immediately denied it- her last name being different was a dead give away against different parenting.
Jun Kurumi was never allowed to assume her father's last name; she was a bastard, therefore would never inherit.
It wasn't until the next day, Kurumi realized the flies all over the school ground of her school application form. Right under family, there was Ayanokoji's school picture. The stares and the questions bombarded her immediately before she ran out of the school in tears as it came out of her bastard birth.
That was the day Jun Kurumi hated Otohori Kyouya.
In completion, this was when Jun Kurumi, by association of those four, sprung hate for the entire Host Club.
