Love Letters generally range from sweet to awkward. But occasionally, they're downright creepy. This usually occurs when a character gets love letters from an obsessive admirer. Typically, there's one creepy letter to start with, but as the recipient doesn't respond, it's followed by dozens more, all written individually and personalized.
The creepiness of the letters can vary, from mild versions where the writer knows way too much about the recipient to extreme versions where the letters are filled with threats alongside the endearments, to anything in between. The one constant is that the letter will always creep the recipient out.

- All of the boss monsters in Gingiva will propose marriage to you, and when you refuse, you are forced to kill them. Each monster has a unique one of these that automatically appears in your inventory afterwards.

- Parodied in the Hardly Working sketch "My Bloody Valentine". Sarah receives a bunch of increasingly disturbing love notes from Pat which contain stuff like "Bee mine?.... THAT WASN'T A QUESTION." Then he kills everyone who flirted with her, and Sarah herself.
- There are gacha machines in Japan that dispense these. They're intended for use as pranks.
