Warning: If you don't know what a Yandere is, it is someone with a love obsess and would do anything for the crush's love. Usually they harm those who loves the crush too and pretends to eliminate them. BTW in this story Chara and Frisk are males. And Chara is also a Yandere. This is totally inspired in Yandere Simulator, so credits to YandereDev. Papyrus isn't the person with the most attention, because he has his own "rivals".
