Fandom oneshot book [Requests open]

[Cookie Run: Kingdom] Simp! Pure Vanilla x Yandere! Reader

Requested by me. I wanted to write something with PV x Yandere Reader because of all my Yandere PV stuff... admittedly I got a bit of help on this... and it's not my favorite oneshot I've ever written because it feels rather out of character and it's not exactly what I had in mind... but still-

Pure Vanilla Cookie couldn't get over this odd feeling he had around one of the Villagers.

They're sweet and cheerful and kind and wonderful and— ahem... but they also had a weird side that they (tried to) keep secret from the healer.

Even though he was literally wearing a blindfold, he could see all sorts of behaviors they had that were definitely not normal.
For one, they were almost always watching him—that's not too odd though... he is the most unusual Cookie the Villagers have ever seen. They also really, really liked spending time with him—not that he was complaining, they're great help when he needs it! Even if it was weird that they could always somewhat tell when he needed help.
That's not even mentioning the fact that sometimes they got pretty short-tempered and that one time he saw them single-handedly rip apart a Wafflebot in rage; and that they also kept the weapon parts of said Wafflebot...

The point is that they were like if someone took a bunch of random attributes from his friends and then shoved them all in one Cookie. They'd had such a two sided personality and both seemed equally appealing and friendly.

"Good morning (C/F) Cookie!" He greets them enthusiastically as he catches them watching him.

"Uh, H-Healer Cookie! Hi! Good morning!" They greet, smiling very widely.

"What are you doing today?" He asks.

"Oh, uh, nothing really." They chuckle. "What about you?"

"Just the usual." He smiles just as wide, "Today seems like a rather good day for a walk if you'd like to come with me though!"

"Sure!" They answer very quickly and enthusiastically.

"Well then let's go right now!"

A quiet day was perfect for their walk.

The two of them, just enjoying each other's company... absolutely perfect. And (C/F) Cookie seemed to think so too!

Could this day get any better?!

"Um, Healer Cookie..." (C/F) Cookie fidgets with their hands, "I, uh, need to talk to you about something..."

"Yes?" He asks, stopping along the path.

"I uh... I really like you." They say frankly. "Like... really like you..."

This... this isn't going the way Pure Vanilla Cookie thinks it's going... is it?

"I um..." They fumble with their words, trying to phrase all the unspoken thoughts in their mind without sounding insane.

Pure Vanilla Cookie would open his eyes in shock if any were visible. He can't formulate anything to say in reply, so he just lets (C/F) Cookie keep talking.

"I uh, actually... I don't think I could just leave it as I like you... In fact it feels like I probably love you a bit too much—Um... How do I put this... I, uh, whenever I, um... actually I won't go into the details..." They shake their head.

"Oh? You can't just leave me with that... I want to know." Pure Vanilla Cookie says before he really has time to think about that.

"I— Well." They grab their hood and pull it over their head more, mumbling as they continue, "Sometimes I just get so angry... I... I'm worried that if I continue on like this that I'll hurt someone... that I'll hurt you..."
