A/N: disclaimer: I am a christian and a senior in high school so in no way am I experienced in college parties or college life, but this was just begging me to write it. Don't take it too seriously lol.

In which Chrom regrets many things

"C'mon, Chrom, don't be a stick in the mud. It'll be fun."

Chrom scowled, and tried to focus on the professors lecturing, blocking out Vaike's whispers. It was hard, because he'd never had much of an attention span in the first place, and second because it was math.

"I don't know, Vaike. Emm doesn't like me going to those parties."

"She doesn't have to know. Really. Libra is even going, and you know how that guy is."

Even so, Chrom was skeptical. "Weird stuff happens at those. Plus, I need to take Robin on a date soon. She's been stressed lately."

"Bring her along! She'd be tons of fun."

"No." The thought of his girlfriend around all those single, egotistical boys was frightening. Robin could handle herself (she once punched Virion in the face for a comment he made), but he would rather not expose her to it.

Before Vaike could comment further, the class was over. Chrom followed his friend out the door, and the rather pointless banter continued. "I need to study-"

"Finals aren't for weeks! Dude, tell me you don't want to, and I'll shut up, but teach senses that you kinda want to."

Chrom was silent for a long time, considering. "Alright, you win. I'm about to become some stereotypical frat boy, and if my very influential sister finds out she'll definitely lock me in the closet, but I'm in."

Vaike gave a loud whoop, and started to run off to his next class. "I'll text you! See ya there!"

After telling Emmeryn he was going to Robin's and telling Robin he was hanging out with Vaike (it wasn't a total lie, he'd make it up to her later), Chrom made his way to the location Vaike had texted him.

The party ended up being exactly as expected. Everything considered, it was decent, and Chrom was having fun, until someone brought out the alcohol. After that, he remembered nothing.

In the morning, Chrom woke up sprawled on the dorm's ratty sofa, his arm stinging awfully.

"Oh, gods. What happened..." Disoriented, he stumbled to the bathroom, where he promptly vomited. "Emm is going to murder me. I can't show up like this..."

But in the cracked bathroom mirror, he noticed something even worse. His sleeve had been torn off, and there, on the outside of his shoulder, was a perfect, peach colored rendition of the mark of Naga, an old religious symbol. He had been tattooed against his will. Or maybe not, he couldn't tell.

"Oh no, no, no. Emm is going to kill me. Robin is going to kill me. I am going to kill Vaike. Oh gods, I am dead," Chrom panicked, running his hands through his disheveled hair.

"Chrom," Vaike drawled sleepily from the doorway. "Whatever you do, really, do not show that to your sisters."

"Really?!" he screeched indignantly.

A vibrating sound alerted him to the phone in his pocket. At least that was still there. When his shaking hands finally managed to hit the button, Robin's cheerful voice greeted him.

"Good morning, love," he stuttered. The phone's display said seven am. How did she always manage to get up so early?

"Did you and Vaike get into any trouble?" Robin asked, concern lining her voice. He must have sounded off.

"No, we're fine. Actually, I have to go...get ready to leave. I'll see you soon, okay?"

"Okay...? I love you."

"Love you too." He hurriedly pressed the end button and stabbed a finger at Vaike. "This is your fault."

Vaike gave him a 'what-did-I-do' look and left Chrom to his existential mutterings.

If he tells Robin I did this I am so dead, he thought.

a/n: fun fact about me, I actually have a tattoo. I'm v proud of it shh.
