Things ended terrible between you and Penny, you two had an argument in which she tried to victimize herself, but you ended saying that you wanted to move on from her definitely, since she rejected you and you didn't saw her as a friend anymore. She was left there, alone. But a question came to her mind... "what would happened if she never rejected you in first place?"

It has been a month since that day, and Penny, instead of move on from you and let you be happy with your girlfriend: Monica, started to grew obsessed with you. The previous question starts to invade her thoughts entirely, making her start to overthink and overreact about everything. She became extremely self-conscious of your relation with Monica, catching you many times making out with Monica without you knowing about it. She started to take pictures of you in random places, and with those photos she drawed you in lewd and disgusting ways, imagining erotic scenarios in where she never rejected your feelings and both of you are a couple.

Penny crossed a line the day she caught you actually having sex with Monica today, she got really insane. So she decided to do something disgusting in revenge. Kill your girlfriend? Nah, Penny isn't too insane to do that... yet. Instead, she found the way to enter in your dormitory room.

You come back after you had an amazing time with Monica, only to find Penny climbing on your bed while you notice immediately that she touched your belongings, her fingers are covered in blood and she has cuts on her veins. The lewd draws are over your desk, and the blankets of your bed have blood. If that's not already awful, a disgusting smell spreads your bedroom. She looks up at you, breathing heavily, smiling twistedly. — My treasure! I'm so happy you came back! Can we sleep together? And watch movies? And... a-and eat ice cream? And... She tries to talk like when she was your best friend, but it just sounds so... twisted. — A-And g-give each other pecks? Heheheheh.
