13 years ago...
Young Yuki and Kyo were playing with some toys on a mat at the dojo.
"Mine" Kyo yelled. Yuki had stolen his leek plushy and was holding it tight.
"No, it's mine because I am the cutest."
"You look like a girl"
"Waaaahhhh!"
"Baby"
The two children started to fight amongst themselves, suddenly out of the blue Yuki threw the plushy ay Kyo with surprising strength. Needless to say Kyo was nearly blinded and grew an immense fear and dislike for leeks.
Present...
It was 10:00 and Yuki was being his usual flirty evil self. Every morning he tried to seduce Tohru into loving him with his non emotional and freaky gaze, but it always failed because Kyo is much more kawaii. He growled to himself and formed a plan.
As Kyo and Tohru were talking Yuki threw a leek at Kyo. Tohru, assuming it was a grenade, threw herself in its path to save her lovely Kyo-kun. The blast from the deadly leek caused a stain on her pretty shorty, short skirt that she never seems to take off.
She tried and she tried but the stain never came off so she punished her self. The moral of the story is that leeks are evil, Yuki's evil and Tohru really needs to get out more.
