You always doodled on your hands, during classes or free time, mostly out of boredom but in your delusional mind it looks good so you never really wipe them off.

You were in math class and the annoying– I mean lovely teacher, sanemi, gave the class an assignment to do you of course didn't do anything and were doodling on your hand instead because why not? It's not like he will notice. ... Sanemi noticed. While he was walking around the class to check if everybody is working on their assignment he saw you NOT working but you were in your own little world so you didn't saw him.

"What are you doing." Sanemi asked you crossing his arms, his tone of voice was more demanding for a good answer, what could be more important than working on your math assignment?
