So I'm going to use some names that I like as some of your friends' names because I don't want to keep typing friend 1, 2, and/or 3. Obviously you and the characters are the appropriate drinking age lol but I hope you guys enjoy :)
Zim:
(Normal POV (not your POV lol)) It was your 21st Birthday so of course you and your friends went to a bar (lol). You started off easy with just a beer but your friends said to try something else like a Margarita. One of your friends had one so you thought 'might as well'... this didn't end the way you wanted it too. You loved how it tasted and decided to order another. Your parents didn't teach you much when you were younger about when you become an adult so the only knowledge you have is from your friends who STILL didn't tell you everything. "Hey, Y/n. You have to sip that. It can make you really sick if you don't." Rumi said. (Btw Rumi is pronounced Roomie in my stories :) ) you slowed down a little bit but after your first Margarita, you did feel a little buzz because you don't have a tolerance built up yet. Once you finished you ordered another. "Y/n, dude. Chill with the drinking." Moxie said. At this point you are now a little drunk. "It's my birthday, I'll do what I want!" You replied. You ordered another, and once it was gone... shit got real. You started throwing up and your friends being the lovely assholes they are, couldn't keep you with them all night. "I can't keep her, I work in the morning!" Moxie claimed. "Well I can't keep her either! I have to watch my niece and nephew tomorrow!" Rumi said. Rumi and Moxie looked over at the third slightly sober friend, Zuri. "What. You want me to keep her?" She said. "Well, yea. It's not like you hav-" "actually, Meghan, I have to leave at noon to go to my parents because we leave for vacation." Zuri said. "Well what are we going to do?" Moxie asked. "Take her to her Boyfriends house. Zim was his name right..?" They all three looked at each other and nodded. They drove you to Zims and took you to the door and knocked. Zim opened the door. "Ah, Y/n so nice to- wait... are you okay?" Zim asked. Rumi peeked out from behind you and spoke to Zim. "Hello, uh... Zim..? Today is Y/n's birthday so we took her out to a bar being that she's old enough and she drank too much and now none of us can keep her until she sobers up..." Rumi nervously smiled. Zim took a second before responding. "Very well. I will take care of Y/n while she's in her drunken state." He waved off your friends and took you in his base. "Hi Zim" you looked into Zims eyes and smiled. Zim smelled the alcohol on your breath and it was strong. "Hello, Y/n. So your friends tell me it was your birthday and you drank to much. Is this true?" Zim asked with a slight smirk on his face. "Mhmm." You hugged Zim. Zim tired to moved but you pulled him back onto the sofa. "Stay." You said tightening your grip and frowning slightly. "But Zim has to work, Y/n." Zim replied softly. "Nooo. I want cuddles. I want you to lay with me and hold me and love meee." You said frowning. Zim blushed at the 'love me' part because you two weren't a thing... yet. He felt happy around you and he loved you but he never said anything because he was unsure about how human affection works. He picked you up and brought you to another room that was soon to be your room at his base for when you visit. There was already a bed and a nightstand. He laid you down and walked to the other side of the bed and crawled onto it. "Please stay with Zim~" you said. He patted your head but remained silent. You cuddled with him for the rest of the night. It was a great night.... until you woke up. Massive hangover, your head was throbbing and you felt like you wanted to die. "Y/n-human, what is wrong with you.?" Zim asked. "The regret that comes with drinking..." you rolled over and said with a raspy voice. "Ah.. So you have, what earthworms call, a hangover." Zim said. "Mhmm.." was all you managed to get out.Dib:
Today was a very bad day for you. Anything you done wasn't good enough or right. Your oh so beloved boss had the audacity to accuse you of some random bullshit that happened on your day off. Once your shift had ended, you went home. Once you got back (you live by yourself in this one btw) you walked to your walk-in pantry and seen your small stash of liquor. You called Dib asking him to come over for dinner because you thought a nice dinner would be the nice being that your whole day was shitty. You decided on something more simple but still fancy.. Like pasta or grilled chicken breasts. (You can chooses either one, idc lol :) ) After you finished cooking, you heard the doorbell ring. You open the door to see you boyfriend, Dib. "Heh, just in time. I just finished the food." You giggled. You signaled for him to come in. Dib was hit with a wonderful smell. "Whatever you made smells really good." He complemented. "Awe, thank you. I made (whatever you went with XD)" You walked to the kitchen to grab the wine and wine glasses. You went through 3 glasses of wine when you started to feel yourself getting a little drunk. "I'll be right back. I'm going to get a water. Do you need one?" You asked. "No thank you. Are you okay?" Dib asked a little concerned. "Yeah, I'll be fine. Thank you." You replied. You returned with your water but still continued to fill up your glasses. You could tell Dib was getting a little drunk as well because he started laughing more than usual. You on the other hand was to the point that you could officially say that you were drunk. Not blackout drunk, but still pretty drunk. "Okay babyy, I need to put this up before you get drunk." You lazily smiled at Dib. He had to help you because you kept tripping over your feet. After you put the wine up, you accidentally fell backwards into Dibs arms. "Haha, I guess I fell for you all over again~" you said with a flirty tone. Dib smiled right back at you and chuckled. He put you back on your feet and kissed you. It wasn't a long kiss but it still made your drunken mind a little frisky. You grabbed his hand and led him to your room and shut the door. "I've had such a bad day, please make this better, baby~" you said still leaning on the door. Dib fully turn towards you and quickly closed that small gap between you two in a long passionate kiss. (I'm not writing this part because I... just don't want too 😂) and now... Afterglow......And then the next morning a hangover, not to bad because you weren't blacked out or to the point of DRUNK but it was still bad..
