Lesson #9. EXISTENCE of MULTIPLICATIVE INVERSE

"a x 1/a = 1"

Their personalities were as inverse as light and shadow.

She never failed to wield her emotions. He expertly keeps his cool no matter how grave the situation was.

She never fails to lean on their comrades for support. He tended to keep to himself and tried to shoulder the burden, whenever possible.

Her bright emerald eyes shone of all the beauty that life has to offer. His dark coal eyes narrate gruesome aspects accompanying their profession.

But when "crossed", they'd exist as one.

Lesson # 10. LAW of CONSERVATION of MATTER and ENERGY

"Matter and energy are neither created nor destroyed in a reaction, they are only transformed"

Kakashi was a sensei, turned colleague, turned admirer, now a lover.

Sakura was a student, turned colleague, turned object of admiration, now a lover.

There was always something there, though misdirected to another person. What gradually started out as a student-sensei relationship, turned into friendly affection, turned into infatuation; now, something they knew would last forever.

END.

A.N. Please read and review. A sequel (about their relationship and marriage life or something) may come up, depending on the number of reviews. Haha I really hope to hit about 50 or something. Haha
