A Testament to Poor First Impressions: (BETA Ver)

Summary:

After coming home a bit tipsy, Rinne mistakenly thinks Niki is in the kitchen. He soon comes to find out he may have just made the worst possible first impression to the last person he wanted that to happen with.

Notes:

This is what I like to call a BETA fic! A BETA fic is a preview/test if a fic concept. Depending on plotting and future outline there might be a change or two in the final version.

(See the end of the work for more notes.)

Work Text:

In hindsight, there were several clues that should have raised alarm bells in Rinne’s mind. But maybe it was the booze in his system or maybe it was the dopamine from winning it big that night at pachinko that let those warnings slip by unnoticed.

For starters, Niki hadn’t told him he’d be staying over at their apartment that night. So seeing the lights in their apartment on that night was a pleasant surprise. Sure he didn’t always let him know when he’d be there but somehow it had become a habit from their younger days. The other warning should have been the fact that the door was actually locked despite Niki being inside. Niki had that annoying habit of leaving the front door unlocked and while it was a relatively safe neighborhood they should still be safe than sorry. Especially now that they were getting more attention as idols. Cospro’s long meetings on safety weren’t held for just no reason. 

He hummed the new song Crazy:B had been practicing all week as he unlocked the door with his keys. The delicious scent of something being cooked hit Rinne with a welcoming splendor. Niki-kyun’s freshly made dinner after his lucky day sounded perfect about now. If he remembered right he still had a few cans of beer in the fridge, one more can with dinner wouldn’t hurt. However, stepping in he noticed a pair of shoes he didn’t recognize.  Strange… maybe Kohaku-chan or Merumeru stopped by. How rude! Leaving their beloved unit leader out from a secret meeting in his (Niki’s) apartment. So as punishment he decided to keep his presence unannounced and tiptoed in spotting Niki in the kitchen where he expected him to be.

Now here is where he really should have paid more attention. See, he spotted one of his beer cans on Niki’s hand. Now normally this is no big deal as Niki did use beer as an ingredient in some marinades but here he was taking a big gulp! Niki set the can aside with a long satisfied ‘ahh’ and reached up to one of the cabinets to pull out some spices. Perfect! With Niki’s hair held up with a claw clip and out of his way, his lovely neck was all but exposed. How very careless! The very temptation to his dearest lover was nearly unthinkable. Niki knew just how much he loved his nape. Rinne slunk his way behind his boyfriend slowly to avoid making a sound. In a flash, he wrapped his arms around Niki's waist while he pressed a kiss onto his neck. 

“ HEEK– !” Niki dropped the spices in his hand with a gasp. Rinne made sure to suck to leave a mark Niki would later yell at him for. Serves him right! Punishment for not inviting him to Crazy:B’s secret meeting in their apartment.

“Tsk, tsk! First you leave your dear husband out of Crazy:B’s meeting and then I catch you drinking from my beer? Whaddya gotta say for yourself, eh?” He grinned against his partner’s neck. There was a certain satisfaction in seeing his ears turn red.

“...ou…vert…” Niki trembled in his hold muttering something under his breath. 

“Huh?” That's when Rinne finally began to notice those annoying warning flags he had tuned out. For starters, when the hell did Niki bulk up? Sure he was deceptively strong but that didn’t mean he was actually buff. Also his skin was a shade or two darker like when he tanned from summer events they had but it was the middle of November. And… he didn’t have that mole on his neck behind his ear he loved so much… The angry eyes that turned to look at him were grey instead of blue… Rinne felt himself sober up in record time.

“You pervert!” Not-Niki stomped on his foot and Rinne let him go quickly. Not-Niki’s face was bright red from either anger or from embarrassment– he could bet it was both probably. The man swung at him which he reflexively blocked. The man quickly turned off the stoves curiously enough before trying to uppercut Rinne. Haha…! Niki would have done the same but nope this was his reality right now and that wasn’t Niki and yeah fighting in the kitchen would piss Niki off if he ever found out so he booked it into the living room instead.

“Woah– wait! This is a huge misunderstanding! Peace! Pea–” Rinne tried to laugh it off dodging the incoming roundhouse kick. Oh shit! Definitely not his Niki! That form and poise–definitely an experienced fighter. Niki sure as hell didn’t know MMA.

“Shut up!” He lunged toward him. “Don’t care!”

“Sorry-! I thought you were Niki!” Rinne said, hopping over the couch.

“Huh?! You do this to Niki?! You disgusting pervert! Just die already!” Not-Niki grabbed a vase that definitely wasn’t there last time he was in the apartment and tried shattering it over his head. Okay time to split before the neighbors called the police.

“It's a bad time– got it! Let’s clear things up later! Sorry man!”  Rinne ran out the door and slammed it shut behind him. In his panic he accidentally shoved a woman walking toward the apartment holding groceries bags. He silently cursed himself as groceries spilled everywhere. 

“Sorry ma'am!” He paused to help her up when felt the hairs on the back of his neck stand up. He ducked just in time to see a pot fly past him. 

“Darling?!” The woman looked at the man in surprise. 

“Stay away from her you pervert!” The man yelled, throwing a kettle this time. Oh fuck!

“Sorry! It's a misunderstanding!” Rinne took that as his cue to leave and sprinted as fast as he could from the place when he heard the other apartment doors start to open. 

He didn’t stop running until he got to the train station. Once he stopped catching his breath he looked behind him and saw nothing but tired salarymen giving him an odd look before looking away. He looked down and saw he wasn’t even wearing shoes. 

Rinne slowly processed what just happened. He sank to his knees covering his face and groaning in fresh despair. 

…Oh no…

…Fuck…

…He just pushed Niki’s mom to the floor…

Even worse–

…Rinne just gave Niki’s dad a hickey…

If there was ever a testament to poor first impressions… this was it.

Notes:

Kyaaaaaaaaaaaaaa! Rinne-kun what did you do this time?! How will he resolve this? How will he even look at Mr. Shiina in the eye? What's Niki going to say?!

God this was so much fun to write. I reeeeeeeeeeeeeally want to write this fic soon. A short fic compared to what I usually write but I didn't wanna spoil too much. Niki's parents come home and the shenanigans/drama after Rinne makes a poor first impression. Look forward to it soon!

Huh? I just realized that all of the BETA fics so far have a similar-ish theme??? Guess I'm craving for comedic misunderstandings ahaha!

If you wanna see more of this fic, please let me know! What are your thoughts?
