Undertale x male reader - A bullet to the head *Season 1* [Completed]

Something fishy

"I bet your happy we've had some food now?" Frisk smiled at Y/N as they left Napstablook's. She then turned to Napstablook, who was standing at the door, before waving. "Bye blooky!" She called out to him.
"Byyyyyeeee." The ghost said in his usual sad tone.
"I guess... But you didn't have to interrupt Napstablook... He didn't look like he wanted us there." Y/N thought back to his time at Napstablook's.

He remembered his particularly sad demeanour. He didn't even greet Y/N, he sorta just... zoned Y/N out entirely.
"No chance." Frisk stated with a smile. "Blooky's just shy that's all. He didn't mean to come off as rude." Y/N looked at Frisk. He didn't entirely believe her. Napstablook seemed off. Almost scared of Y/N. Like he could tell that Y/N was a bad person or influence but... was he wrong. In Y/N's mind, definitely not.

Y/N still felt like a dick. Especially, how he had hurt Frisk emotionally twice now. He carelessly eased dropped on Chara. Asriel definitely didn't like Y/N and he understood that. To some extent, Y/N hated himself. Yet, he wasn't ready to confront his own demons just yet.

"Well anywhere else you plan to take me before we get to hot lands?" Y/N asked Frisk as Frisk seemingly chuckled.
"I thought you wanted to go after that checkered suit man." Y/N stayed silent for a second as he thought of the best way to answer.
"I do... But at this moment in time you and Chara matter more to me." Y/N gave his honest thoughts as Frisk smiled.
"See, your changing."
"Huh?" Y/N confusingly stared at Frisk.
"When we where at snowdin. All you thought about was your revenge but now you care about other things more. Such as me and Chara."
"*sigh* what are you talking about? I'm still a bad person. I still want them dead."
"But you can change. We... we can save you." Frisk looked at Y/N this time fully revealing her eyes to Y/N as she stuck out her hand to Y/N begging him to accept, to which he did.

(...)

Naspstablook shut the door behind him as he send the group on their way. His thoughts were immediately brought to that man, who he had just fed. Shivers went down Napstablook's spine. He was worried for Frisk, Chara and Asriel. Y/N seemed like he could potentially be an issue.

A few moments ago

Napstablook watched carefully as Y/N slowly ate his cereal. Y/N looked determined. His thoughts completely on the gang that attacked him. Unbeknownst to Y/N, Napstablook was one of two people that could read him. Sans and Napstablook, they both could read Y/N like a book.

Y/N seemed angry, hurt and sad all at once. Napstablook peered into Y/N soul as he saw something pop into his view.

[Y/N L/N. Check?]

Napstablook pressed check.

Y/N L/N, hatred fills his body for the man that harmed him. His sadness, his pain, being the only thing left after the... incident.

Napstablook stop checking him. His head spinning as he worryingly looked to Chara, Frisk and Asriel who were happily eating their food whilst chatting. Y/N seemed quietly uninvolved in the conversation.

That word kept playing in Napstablook's mind, incident. What had happened to make Y/N hate as much as he did?

The current moment

Napstablook, seemed scared as he took out his phone and called someone.
"Mettaton... it's Napstablook."
"Blooky darling! How amazing is it to hear your wonderful voice again!" Mettaton called back with his mesmerising voice.
"Hello..." Napstablook said shyly as he wondered whether he should hang up or not but for Frisk's sake he persevered.
"What gives me the pleasure of hearing your voice once again Blooky?"
"It's Frisk-"
"Ahhh my one true love!"
"Y-yes. I believe she's in danger."
"Oh no! What makes you say that, blooky?"
"There was this strange guy and I think he's... not good."
"Oh right! Well do not worry blooky! Mettaton will be on the case!"
