First encounter

Arthit is new at university, but the first thing he does on his first day is to create an enemy feared by everyone.
But Arthit knows how to use his fists. Or should he rather use something else to defeat this enemy?

The characters are not mine, neither are the pictures, they belongs to the respective owner.
Only the story and the plot are mine.
It will be a short story. No angst, no silly breakups (i don't like it). Fluffy, funny and sexy.
