Pool cleaning was canceled for the day. Classes went on unusually normal.

Chizu seems to have forgoten what has happened, and so does the other students.

"Look Y/n I'm really sorry I dont remember anything... Here to make it up to you, how about we stop by the ice cream parlor later? My treat"-She offered.

"Oh uhm it's okay Chizu, I know you're busy too and I have something to do at the library later. So maybe next time?"-you said.

Just as Chizu nodded the bell rang. You waved her goodbye and went to the library.

You where about to knock but then the big old wooden doors swung open.

Inside was Tsushigomori sensei seated near the desk by the big stained window.

"Sensei! H-how did you open the door?"-you asked looking behind the doors.

"Have a seat"-he said gesturing to one of the chairs.

As you walk forward the doors behind you shut; it made you jump alittle but you went on.

"Y/n? Strange things have been happening around school lately. Do you know why? Do these dreams of yours, by chance- show you why?"-he questioned.

You try to recall one of your dreams- the first one you've had related to the new school.

"Are the school mysteries related to this somehow?"-you asked.

"Smart" he chuckled. "Did your dreams tell you anythinh else about them?"

You suddenly recall the most recent dream you had.

In the dream you where in school, walking through a corridor filled with students. You can't quite make out their faces. They where all talking about one of the school mysteries. School mystery number 7 to be exact.

"There was one dream.. the students where talking about school mystery number 7-"you replied.

He looked completely taken aback and confused.

"Number 7?.. A new school mystery huh?"-he whispered to himself.

Tsuchigomori sensei stood up and walked towards one of the bookshelves.

"Are you sure you heard number 7? None of my records state anything about a new school mystery comming."-he said running his fingers through the spine of each book.

"You may have been having physcic dreams Y/n. But, we cant be to sure how it plays out in the near future. Since you already know more than you should about the school mysteries- I suppose it wouldn't hurt to show you this."

Just as the clock hit 4; a mysterious door opened up.

"After you"-he said gesturing you to go inside.

It looked like an extension of the school library; except- bigger.

Towering bookshelves pilled with red, white and black books.

"Welcome to the 4 O'clock library! If you haven't figured it out yet- I'm one of the school mysteries, and this is my boundery."

You made your way to one of the bookshelves filled with red books. You carefully run your fingers on each book, feeling all the different textures through each book.

"I wouldn't touch those if I were you"-he said glancing at you.

"Why did you bring me here?"-you asked.

"About that-" he sighed. "One of the school mysteries seem to be messing with your dreams, I dont know what their intentions are- but based on what you have told me... their planning something, something big."

He looks at you cautiously.

"Y/n- they seem to be after you..."

"W-who?"-you stuttered.

"School mystery No. 1- The clock keeper.."
