Who?

Olen looked at the glass bottle in his hand. There was some white powder in it.

But when this ma broke the other bottle Olen didn't see anything coming out.

That means this thing is either something different or the chemical becomes transparent when it comes in contact with air.

For now, he kept the bottle with him. He would ask his teacher when he gets back.

He quickly cleaned himself up and again checked if there was any blood that fell on him.

He was very careful not to touch blood. He even left the dagger in the dead man's body so the blood doesn't spatter on him.

After finding everything to be fine he wore his overcoat and quickly came to the group.

"Hey what happened?" –Monica asked looking at Olen.

"Wha… nothing." –Olen said.

"Hmm…" –Monica came close to Olen and reached her had toward him.

Olen got a bit tense.

Was he caught already?

He was really trying his best to hide it though.
