Dangerous Love (Yandere X Reader)

you are in High school, at the most amazing school youve ever seen. the building itself was beautiful, and the teachers and other staff members were all very kind, even most of the students were friendly.
when you were in elementary school, you had your own small group of friends. Six boys, and three other girls. well, i guess i cant really say it was a small group with all of you there, but you get my point. After this year, you have to leave the state because your mother had work in japan. you know of this long before you leave, so you were fully prepared, but until now you hadnt told your friends. you knew that after that year you would be leaving. leaving all of the friends that you have had since kindergarten. you dont want to leave. you love your friends. and they all love you. but what if you didnt have to leave? or... what if you... cant... leave?
