Its been 5 months since you applied to your current office, you never noticed anything wrong and odd.

you're a clumsy person, this morning you accidentally tripped and you accidentally cuts yourself, which left a mark in your hand.

you doesn't bother about it too much. This evening you went into your senior's office, artem wing. You handed the papers he asked, but he suddenly held your hand. He noticed the cut wound in your hand.
