It was the Year 199X Sunny and Omori was born.

Sunny had always been abused by his father even before he was 5, his Father was aggressive and kept telling Sunny that he was an "accident." And that he wasn't supposed to happen, While Mari and his Mother did theri best for him, His father couldn't bear Sunny. He was the Perfectionist of the Family, a Perfect Family is a Mother, a Father and an only child seeing sunny be in his "Perfect." Family had made him often very aggressive to Sunny. This would later create Omori, Omori was...a completely different personality from Sunny, just like his father he was vey aggressive and devoid of all emotions.

Sunny had immediately recognized that there was..."something wrong." With him as he always kept saying "We." In times where he was supposed to say "I."  And he would often have Memory gaps and their co-consciousness would always comment on certain things, Often times to be negative.

But as far as he could remember, there was..."Nothing wrong." With him, Mari and his mother still saw him as a good boy and despite in his head being all bad and all, with memory gaps and everything it made him feel weird.

It didn't take long but he later figured out that from the writing, the negative comments...he figured out that he must have had another Personality and in his mind he viewed the other Personality as a hostile version of him...He didn't want it and in the headspace he began trying to have a clearer communication with his other self which he succeeded

He pleaded for Omori to not be aggressive as he promised to Omori that everything will be fine, Omori argued back and the two argued foe awhile before deciding that Omori stated that he will do everything in his Power to try not to be openly aggressive and that he will do Chores perfectly as a distraction but the moment anybody is any aggressive to him is the moment Omori will do everything in their power to hurt him.

Sunny appreciated the Compromise, it was good that his father began treating him Nicer as time went on, Omori would take over for awhile but he would be there to do everything perfectly as a means of distraction while Sunny had fun with Mari and the friends they made, Notably Hero and Kel which was not hard to make friends with as their parents were friends with eachother.

Nothing could go wrong, everything was going perfect! And overtime they made new friends, Aubrey and basil! He always loved making new friends and Omori was there to do everything that wasn't fun for him...Like Chores!

It was the Day of the Recital

Months and Months went on as Mari had done nothing but pressure Sunny into perfecting the Violin, Sunny had continued to Beg Omori to spare her as she had done nothing but be a good sister.

But Omori thought otherwise.

Omori had taken the role of a Guardian and while he didn't like doing stuff, it had distracted him from ruining not only Sunny's life but also his life but Omori just couldn't understand...why was he so emotionless? And why did he do everything so aggressively? He just wanted to be a normal person and hang out with them like Sunny did.

He at one time tried to hang out with them but they thought "Sunny." Was being weird and at one time he went aggressive on them , Sunny later apologized and stated that he was stressed because of the homework which led to everybody helping Omori on the homework...it was a weird way of hanging out with them but it was fun...he still didn't like being called Sunny, Omori was his name for Christ sake!

But Omori could see that Mari was being a bad sister and Sunny spent most of their dreams portraying Mari as the "Perfect Sister." When infact she was far worse than that.
