Freaky...I love it :D

Mother of all-holy Christ, how did you manage to make someone so relentlessly cheerful so terrifying while still being in character? It reminds me of a lot of theories about "self-learning" AI: it only learns what you show it, without any natural context, and so if you show it the wrong things, or even the right things in the wrong way, results can be...Messy.

Thanks for writing this man, awesome work. You're one of the best in the fandom.

Well...that's pretty unsettling.

This isn't creepy and unsettling at all.
I'm not scared, you are.

This reminds me of Yandere no Onna no Ko Drama CDs. _

This is creepy as all hell. My god you make good yanderes.

If I get laser beam eyes I'm down with this idea. Also good story, it reminds me of the short film ABE.

Yandere Penny. I am a firm believer that having a psycho in love with you is far more horrifying than having a psycho hate you.
Cool, creepy and I can kind of see this happening to Penny considering her lack of social skills. The fact that I didn't find a single grammatical or spelling error is just the cherry on top.

Also, was the part about love being printed on Penny's circuits a reference to AM's (from I Have No Mouth And I Must Scream) speech about having hate printed on all of his circuits (that still would not equal one one billionth of the hate he feels for humans. Hate. HATE.)?

Is there going to be a prequel story with Ruby becoming the unwitting instigator of this person's doom? Or a sequel that shows the vicious cycle of Penny meeting and 'improving' other lovers?

Closing thoughts: Cool story bro.

Very nice and creepy. A good story.
Well done, Wolf out.
