All in all, having Moldy Voldy here as a platonic yandere would literally suck. Having him as any type of yandere would suck actually, one look at his face your morning will be ruined

And it's not like his appearance gives anyone comfort, his terrifying appearance makes people run in the opposite direction screeching on top of their lungs. And rightfully so, he is the most powerful and evil wizard in the wizarding world, a literal psychopath if you will

As soon as he sees you, you'll have to kiss your freedom goodbye. He'll either send his minions, the Death Eaters to stalk you and if you already have someone else you like, welp.... they're going to die. And as for your parents, if you're a pure blood, he'll talk with your parents to hand you over to him without complaint before things get messy. Same situation if you're a half blood but if you're a muggle, then he'll just straight up murder them and snatch you away like a feather and Obliviate your memories, and trick you into thinking that he's the only family you've ever had

You of course would be terrified and scared out of your wits and who wouldn't? You literally got kidnapped by Voldemort here, and you're bracing yourself for the flash of green light that he'll kill you with but much to your surprise, he said he isn't going to kill you and in fact wants you to be with him. What? Were you hearing right? The infamous Dark Lord wants you to be with him?

He might not seem like it but he's really over protective of you. Even though he sometimes acts like he won't really care, but he totally does. One good thing from him being a platonic yandere for you instead of a romantic yandere for you is that at least he won't torture you and inflict punishments upon you for mere pleasure. On the contrary, this dude here will FLIP if something happens to you. One time, one of the Death Eaters accidentally smacked you on the face and the next thing you know, Voldemort just crucified him for hours together, making you listen to his screams and yells of pain. He deserved it anyways

He also has this uncontrollable urge to always correct you no matter what and somehow, he gets pleasure from that. He gets amused whenever you make mistakes and he'll seize up that chance and golden opportunity to correct you and lecture you. If you make that mistake again and again, he'll have to put you under the Imperious curse or the Cruciatus curse, since that's the only way you'll learn. He has to be strict if you need to learn and grow up to be an influential and powerful wizard/ witch

You'd expect him to get angry if you slip up and accidentally mention Harry's name, but rather he's actually interested in learning about his weaknesses from you. Bonus if you've actually been friends with Harry. And even if you don't want to tell him anything and you're playing coy with him, please, I advice you don't do that. He'll find out eventually, and he'll either slip some Veritaserum in one of your daily glasses of pumpkin juices or water or he'll put you under the Imperious curse to make you start talking

Bold of you to assume this man here would even initiate things like hugs and stuff. But he won't necessarily be opposed to any form of physical affection from you. He won't mind it at all and he actually sort of likes it. One time someone made fun of you for hugging him and the next thing you know, Voldemort here was threatening him that if he dares to utter something like that ever again, he'll slice his tongue off and feed it to Nagini

He'll let you attend his meetings as well but you'll of course, have a book to read or some or the other activity that you'll enjoy doing. You don't really need to get into the dark stuff yet. He doesn't want you falling into danger just yet, as ironic as it sounds. And if you still want to go back to Hogwarts, you can either attend by the name of the Riddles, or the Malfoys, or any other pure blood families name. And if you're not in Slytherin, he'll not bother sending you there anyways, he thinks you're going to be corrupted there and so he'll resort to teaching you himself

He acts like you're too silly and naive and you need someone or the other for life, but in reality he just likes taking control of your life, it greatly pleasures and amuses him till no ends. Sadistic prick. But if he's ever away on some business, he'll leave you in he hands of his loyal followers and they'll actually treat you pretty well since they don't want anything to happen to them after he comes back, they very much like to remain in one piece

All in all, don't test his patience too much, he doesn't like it when you act up and please don't, for the sake of your safety and sanity. It'll be pure hell if you do. Voldemort won't ever give you up, he'll keep you by his side till the end of time....
