He's a physically affectionate yandere, who prefers to show his love to you by hugging you, touching you all over and basically in his point of view, showing and proving to the world that you're his and only is. But there's a teensy little drawback to that idea of his: You're touch starved and you absolutely HATE and DESPISE being touched since you haven't been hugged or received any physical affection in so long. It made you get panic attacks and you'd start to get dazed and hyperventilate and unfortunately Malfoy found out about your little complication the hard way. You and Malfoy were sitting on the couch with each other after doing your potions homework and you had no idea he was obsessed with you. He's been trying to ask you out since, forever but either you're absolutely innocent and clueless about his feelings and advances towards you or you're just messing with him. Either way, you're proving to be a challenge and he likes a bit of a challenge from time to time. So, when he was thanking you for keeping him company, he slowly grabbed your hand and gently pulled you closer to him as you looked at him with confused and fearful eyes and he suddenly hugged you. You started hyperventilating and struggled to get out of his arms and Malfoy was immediately concerned and he quickly let you go as he gave you a glass of water and asked you if you were all right

"NEVER TOUCH ME AGAIN WITHOUT ASKING ME!" you swatted his arm and glared at him but you had a fearful look in your eyes and he wondered what could possibly have triggered this sort of reaction from you. He simply had to find out and he made a mental note to talk to you about it later on when you were feeling all right but right now you needed some comfort. He handed you some water and you gulped it down as he rubbed slow comforting circles on your hand. After a while you told him that you didn't receive any physical touch of any sort since a really long time and you had no idea how to react and he immediately felt sorry for you. Oh you poor thing, you mean to say no one's hugged you in a really long time? Don't worry, he's going to change that for you. But he's going to take baby steps since he doesn't want to overwhelm you after all and he'll be there for you whenever you have your panic attacks

Harry Potter: Surprisingly, Harry will understand what you're going through and he's going to be really understanding of the situation you're in. Harry is another yandere who'd like to hug you and wrap his arms around you protectively so he gets the feeling and the sense that he's protecting you from something. Ever since his last battle with Voldemort after the Triwizard Tournament he's been really paranoid about someone trying to steal you away from him or anything happening to you really, he's really in love with you. He's MADLY in love with you and his heart aches and longs to be with you for life, just you and him together. No one else. After all the stuff Harry's been through, he's been a bit skeptical about being physical with anyone or even trusting anyone for that matter but then you came along into his life, something he's really thankful about. You gave him hope and you occupied his mind every single moment. He finally asked you out and you agreed to go out with him much to his happiness. The first time he hugged you, that's when things went south completely

You and Harry were on the Gryffindor's common room's couch and Harry slowly snaked his arm around your waist subconsciously and you moved up with a sudden jerk and you fell from the couch looking at him with wide eyes. "Wh-what did you try to do?" you asked him and he felt a pang of hurt stab right through his chest and twist into his ribs. You were making him feel like he's trying to do something wrong with you, he looked concerned and bent down and spoke "Y/N darling, you all right?" and he tried to touch your forehead but you pulled away instinctively and whispered "I don't like people touching me. I'm-I'm scared... it's been so long since anyone's tried to hug me'' and he felt really sorry for you and a bit of anger surge through him. Not at you of course, at other people. At society, at everyone else who you've had in your life before him who didn't show you the proper love and care you deserved. He made sure you were comfortable and told you that he could relate to what you were feeling and he promised he'd take it slow. When he asked you if he could hold your hand, you contemplated over the thought for a few moments and you finally nodded, to Harry's immense happiness. You were slowly trusting him, that's good. He's going to take it really slow with you and he might not be that patient with the other people but with you, the man has endless. He really does love you after all with all his heart, would even go as far as burning the entire school to ash if something happened to you

Fred Weasley: Well, you being touch starved with Fred here would make him just sad. Really really sad. He wants to show you his love and affection and shower you with hugs and kisses. He remembers the first time he's met you, he was instantly captivated and smitten with you. The way your mesmerizing eyes held some sort of mystery behind that kind sparkle in them, your adorable and endearing laugh and heck, he even remembers what was the color of the dress you were wearing, he was wearing and even the weather conditions. He noted it all down in a little notebook dedicated to you since he liked to keep track and tabs on your day to day schedule. Most people would refer his behavior being obsessive and point out that he's being a stalker but is it really that bad to make sure your loved one is safe? After all, in a place where Dementors and Death Eaters can barge in anytime, he needs to make sure you're safe. He's also really paranoid about your safety and that trait of his was what contributed into him kidnapping you and having you for himself

The first few weeks was your adjustment period with him. He was willing to forgive all your little tantrums and give you some space since he knew you were scared. Eventually you'd settled with him and calmed down since he was treating you really well and he claimed that he loved you. So you could sit back and relax right? Eh, try again. He was really affectionate with you, always wanting to do some or the other thing with you to spend time with you. But when he tried to hug you during your sleep and cuddle with you, you swatted his hand away and told him not to touch you. He looked like a kicked puppy and felt guilty that he made you feel uncomfortable but you told him you hadn't been touched in a while or hugged for that matter and he felt like being your hero and holding you in his arms forever and ever and never let you go to prove how much he loves you. But he knows it'll overwhelm you and that's the last thing he wants. No worries, he'll just take it one step at a time with you

Blaise Zabini: Blaise here as a yandere isn't really that physical with you unless and until you desire it. The last thing he wants is for you, his beloved to feel any kind of uneasiness or nervousness about something that he's done. But he DESPISES it like anything when he sees you talking with someone else and the other person was diverting your attention from him, your future spouse/ husband. Don't you know that you're his? You belong to him and solely to him? What's a guy to do to get the attention, love and care from his beloved? Oh wait. He just answered his own question. He'd immediately kill them without you knowing of course and THEN, he'd have your attention for himself. Inside his mind he'll be thinking 'She's mine, ALL MINE' in that evil voice of his looking all smug

The first time he's tried to get physical with you was when he tried to hold your hand. A sweet and simple gesture on his part so as to not overwhelm you with the amount of love and affection for you because dear LORD, the amount of love he has for you would not even fit in an OCEAN. You and Blaise were on his bed reading a book. You were engrossed in your book and Blaise thought you looked rather endearing. He could watch you read all day long and not get tired, you looked ethereal, like a true angel. An epitome of perfection in his eyes, flawless even by doing such a simple act. Overcome with intense love for you, he needed to hold your hand as a sign of comfort for him to reassure himself that you were indeed there with him and wasn't just some sort of trick fate was playing on him. He intertwined his fingers with yours and you instantly flinched and pulled your hand away and told him not to do it again. Of course he wouldn't do it again without your permission but he needs to know why you've reacted like that? Who does he need to kill for making you uneasy when it comes to physical contact? When you explained to him that it's been a while since you've received any affection from someone and he's understanding as well as a bit pissed too. How can an angel like you not receive affection? He made it his mission in life to make you receive as much as love and affection you've missed from your past and he's a determined person. Once he sets his mind to something, he has no intention of letting it go
