It's been a while since Harry's harbored less than normal feelings of love for you, it was an obsession, an unhealthy one at that. He was sinking into a madness and an ocean of love for you, it's like he's consumed Amortentia for breakfast, lunch and dinner. He's stalked you for a pretty long time under his invisibility cloak which was really useful for following you around to keep an eye on you to make sure you were safe. He does have a good reason you know, in a place like Hogwarts where Dementors can attack at any given point of time in the day or Death Eaters or Voldy himself can come in any time and attack everyone, he NEEDS to make sure you're safe. He cant' feel at peace unless he knows you're safe which proves that he's really paranoid about your safety. He's confessed his feelings for you after Ron and Hermione kept needling him to do so and Hermione said in exasperation "Harry, if you don't tell Y/N how you feel about them someone else will do so'' and Ron nodded in agreement and replied "Yeah mate, you better get to them fast. I hear that prat Malfoy likes them'' and Harry's eye literally twitches in anger. How DARE that git try stealing you away from him?

So, the next day itself, out of fear of someone stealing you away from him, he finally confessed his feelings to you and he was relieved when you accepted his feelings. You decided to accept his feelings since you both were good friends after all, you trusted him, he couldn't possibly do something dark and psychotic to keep you bound to him forever and ever, right? Oh, you my dear, had no idea how wrong you were. But Harry was thrilled, he couldn't stop smiling like an idiot throughout the entire day. Heck, even during Potions class, not even Snape could dampen his spirits. You and Harry spent your first Christmas together at the Gryffindor common room and when he saw you wearing his sweater, he felt pride and a warm feeling of happiness surge through his chest. You blushed when you saw him and told him that you felt cold and you didn't have any jacket or sweaters with you that you could use since they were in the wash. He wrapped his arm around you comfortingly and told you to keep it, you looked beautiful in it. He made a mental note to make you wear more of his clothes and make sure everyone else at Hogwarts, including that annoying blonde haired git Malfoy saw you with his clothes, so he'd know you belonged solely to Harry and no one else

Malfoy here is a bit of a sneaky and calculating yandere. He KNOWS how to get his work done somehow or one way or another. Literally doesn't give a damn even if he has to play dirty every once in a while, if he gets to have you for himself, he's even willing to go as far as killing people for even daring to look at what's his. The way he sees it is you're his. That's it, end of story, so people should know better than to mess with a Malfoy of all people. Malfoy would tease you and make fun of you sure, but wouldn't harm you physically, he isn't THAT much of a jerk. He doesn't want to harm the person he loves, for Merlin's sake, he's not some sort of monster. he resorted to stalking you and teasing you as way to show you his affection. But one day when he made you cry with his words he didn't know why he felt so horrible and he knew he messed up big time and needed to get back into your good books. So he started being helpful and didn't call you anymore names and pleaded with you to at least give him a chance to be your friend. You agreed and that's when things would start going downhill for you from there

Malfoy wanted to be much more than friends with you though, so when he confessed his feelings for you at Hogsmeade, you felt nervous since you didn't want to go out with anyone just yet and you told him you just saw him as a friend and let him down gently. He pretended to be understanding and chill but inside he was raging, how could you refuse him like this?! Can't you see his heart is breaking to pieces? There HAS to be some other pathetic lowlife scumbag in your life, doesn't matter what the gender is, whoever the hell stole you from him would HAVE to pay with their life. If it was that Saint Potter, Malfoy would loose his cool and do whatever he can to kick him out but fortunately, you weren't really going out with anyone just yet and he understood you were nervous and scared. It's all right, it's only natural you be scared of something strange and foreign, but he needed to earn your trust. So, he used the disappearing charm on your clothes and he offered you his clothes for the time being, till you could find your clothes. When you wore his clothes, his heart did a double take and he felt like he was soaring in the sky on one of the broom's, you looked really endearing and cute. He wanted you to wear his clothes, seeing you wear his clothes made him more possessive of you and it was like a way of saying you were his by default

Neville as a yandere would be really shy and self conscious of himself. He thinks you're a literal and complete angel and he doesn't deserve to be around you. He thinks he doesn't deserve your attention and time but at the same time it just pains for him when he sees you talking to someone else other than him and when you're laughing with them. He wants to spend time with you, he wants to be the one to make you laugh! You and Neville are good friends with each other and since he doesn't want to ruin the special friendship you both have with each other by telling you how he really felt about you and making things awkward between you both, he just buried his feelings for you. But Ginny offered to help him and you actually liked Neville, he was shy, sweet, charming and caring and not to mention sensitive to other people's feelings too. Besides, he was also adorable and you liked spending time with him. When you told him that you always had fun with him and liked spending time with him, his heart raced and hammered against his chest and he felt like he's been soaring on a Firebolt in the air at a really high speed

Neville wanted to ask you out but was too scared of making the first move, but at the same time he'd distract you whenever someone else was about to confess their feelings for you. He knows it's not nice of him to do so but he can't help it, he doesn't want to lose you, he's so scared of losing you to someone else. He doesn't know what he'd do if you weren't in his life and he thanks his lucky stars for the day he's met you. You and Neville were sitting with each other at the tables at the Great Hall for breakfast and there was a package for Neville and when he opened it, there was a Remembrall inside, it looked like his grandmother sent him another one after he'd lost the first one. There were a few jerks from Slytherin making fun of him for it and you got into a fight with them, Neville was trying his best to get you to stop since he didn't want you getting hurt. He'd never forgive himself if you were hurt because of him. The Slytherins spilled some water on you by mistake and when they started leering at you, that's when he got angry and he hexed them and offered you some of his clothes to wear. He thought you looked ethereal in his clothes and couldn't stop blushing like crazy, his face was a literal tomato. You thanked him for his clothes and gently kiss
