Stuck between worlds

"You have to choose" "We all love you and care for you and respect your decision" "Just please choose carefully" words from the three guys y/n has a hunger and desire for but can only choose one who will they pick. In a world where things must come to an end, y/n, dumbledore's grandchild, they come as a first year and meet many people who: are tom riddle, draco malfoy, harry potter and they find themselves in a love square between the guys and themselves. Two guys (tom and draco) learn from y/n and realize many thing that they once believed in were wrong and y/n didn't change them in a bad way but rather in a good way, she allowed them to see the world and many other things in a new way, in a new perspective . They have to choose but don't know how they can't compare the guys because they're all so different but then they come to a realization and choose who they hope is the right guy. But truth be told they're not always soft fairy tales and it's not easy with the three guys with rough past and it takes them a while to realize they actually might be falling for someone who they don't expect . This is 'Stuck between worlds' (in this story tom riddle isn't voldemort, and you guys are all in the same year but tom comes in the ending of 2nd year) *SMUT WARNING* *STRONG LANGUAGE IS USED*
*this won't follow exactly like the books or movies it will have the same story line but some things are different *
