13 SENTINELS: Aegis RIM: ANOTHER STORY - [PART I] (BOOK I)

11.7. FLASHBACK: Y/n's Perspective: Three Weeks Ago: In Y/n's Room

[THREE WEEKS AGO...]
[FLASHBACK: TUESDAY AFTER SCHOOL...]

Y/n and T/n was already home to meet and talk to some relatives.
The two had homework and since they have classes together, they decide to help each other out as they always do.
Their parents and other relatives left to hang out for a bit before dinner time, so the twins currently had the house to themselves.

They settled in Y/n's room for a study session.
Making an agreement on which subject to start on, they go with history first.

T/n took out her history book and notebook from her bag, and so did Y/n.
One problem though...
Y/n couldn't find her notebook anywhere.

Y/n:  "I don't have my history notebook."

T/n:  "Try checking your room."

Y/n immediately went to searching her room with T/n's help.
A few minutes later...
No history notebook was found.

Y/n:  "Nope, not in my room either."

T/n:  "I'll help you look around the house."

A few moments later from searching...
They came back and grouped up in Y/n's room with no results of finding Y/n's notebook.

T/n:  "It's nowhere to be found."

Y/n:  "The last time I had it was in class today."
Y/n:  "I think I might've left it at school in my desk."

T/n:  "If you go now, you'll have time to get it without getting locked out from the classrooms."

Y/n:  "And plus, school is not that far from here."
Y/n:  "I'm gonna go now and retrieve it."
Y/n:  "You can work on it without me."

T/n:  "Please have a safe trip."

Y/n:  "Thanks, I will."
