(This is specifically a Oneshot requested by Enya on my Yandere Oneshots book. I have decided to release it all at once on there but on here It shall be split into five parts including one prologue and an epilogue. You may choose to read it on my yandere oneshots, but if you enjoy to have the story more chopped up then I'd suggest reading it on here. if any sequels are requested I will also upload it on here~Skele)
