Chemistry Has "Reactions"

"One boy upset over his soft, cute appearance. The other boy, because of that boy's pretty and cute appearance, deliberately provokes and fans his anger to reveal his own Masochistic traits. What will happen between them?"

The story begins with random scenes from the boys' current friendship before taking an in depth look back at how these two began.
