The four boys and their yandere types.
Dave: Aggressive Stalker/delusional Yandere. He likes leaving gifts for you. Roses, dead animals, chocolate, you name it he’ll leave it. He’ll also send you his favorite pictures he’s taken of you-How did he manage one of you in the shower?!-. He won’t approach you, and if you do end up dating him it would be of your own volition, not knowing he’s your stalker. It’ll only get worse once you do start dating him, the gifts will increase and he’ll have a hard time not letting slip he’s the one who leaves all of them, as he wants the validation for the gifts. The delusional side will always show that you have to love them and him no matter what, and he probably already thought you were dating before you asked him.
John: Two faced Yandere/Cutesy Yandere. Very hard to tell that he is a yandere at first. He does his absolute best to be sweet and kind and forgiving, the kind of clenches fist when he sees S/O talk to anyone else, adores you and clings to your arm, but never enough to be truly worrying. He just wants to love you, but he’s also likely to snap at too much, and be worse than a sadistic yandere at that point. If you turn down his affection he’ll snap and then he’s REALLY all over you, and tends to be the kidnapping type.
Jake: Aggressive Stalker/manipulative Yandere. Similar to Dave in leaving gifts, but also is the shoulder you cry on in fear about the stalker. Promises to keep you safe and even stay over just to make sure you aren’t too worried about the stalker. His goof ball idiot act makes it all the more convincing too, until you’re falling for your hero, not realizing that the stalker doesn’t seem to mind him.
Dirk: Silent Stalker Yandere. Very in control of the situation, planning out every meeting he has with you down to the very last detail. Nothing is an accident when it comes to Dirk. He knows your favorite food, all your allergies. He isn’t the kind of stalker that gives gifts, rather the one that has a huge shrine dedicated to you, and just wants you to be totally happy, with him.
