It's already uncomfortable enough to camp outside without a roof. Adding your overprotective brother into the mix seems to make everything worse and not to mention, a girl that seems to be a little odd or 'yandere' as per Lune's understanding through a certain country's animation culture from her past life.
First off, Sol can't stop watching like a hawk at everything Chilve does. Secondly, Vivian seems to be over excited on the premise of getting to know Lune better and doesn't stop pestering her with endless questions. Thirdly, Chilve seems to be more concerned with Lune and keeps asking if she needs any rest and get attentive, which makes Sol grumpier by every passing minute.
'Get a hint, Chilve! Stop worrying about me and just worry about yourself!' They finally reach somewhere suitable to set up camp, where the crescent moon shines brightly above them without any clouds, which makes the night chilly than usual. Lisa and Vivian went ahead to get the firewood for their campfire, and that leaves Chilve and the twins setting up a simple tent, where Lune had it made based on her blueprint.
"From the looks of it, this," Sol points at one of the sticks that are supposed to enter the side of the tent, "should be knotted along with the rest of the sticks."
"No, I think-"
"No one here cares about what you think."
"Have your sister told you how childish you can be, right in front of your face?" The blonde huffs and Chilve laughs, "I guess not."
Sol gets up after slamming the stick he was holding on the ground, "are you asking for a fight? Because I'm willing to grant that request of yours."
"I don't want Vivian to be moaning about how bad your face turned out to be after getting trashed by me."
The two stop what they are doing when two water orbs hit right in their face, just like a wake up call and Lune is fuming, "if the both of you have the strength to fight, set this up quick! Just insert the sticks into the sides, it has an opening at the edge."
"Insert?"
"Opening?"
Lune scratches her head in frustration and takes the sticks, then she starts inserting them through the little opening at the edges herself, which makes both Chilve and Sol stare dumbfoundedly at how easy she makes it look like. Once with all the edges, the tent has the structure and she puts it on the ground, "have you seen enough? Please go ahead and make another tent."
This is the first time they get this quiet since they met today doing something together. While she is thinking about how this should be the atmosphere everyday, the firewood team comes back with lots of wood, "we are back!"
Arranging properly and closely, Sol casts fire to light the sticks, and soon it's raging while Lune nods, "it seems we are done for our night. Good night!" She enters the tent and after Lisa follows suit, Chilve enters and the blonde crosses her arms and stares at him, "what do you think you're doing barging in the tent?"
"I thought we were going to sleep together?"
"You should sleep with Sol while the girls will sleep here. Don't you at least understand the ethics of-" the albino sighs and holds up his hands for defense, "hold up, can you at least hear me out?"
She finally nods giving her consent and he continues, "Vivian just begged to sleep in the same tent with your brother, and I can't really disturb their alone time, can I?"
"Wait, what?!"
Lune barges out from the tent to enter the other, where Sol seems to be struggling from Vivian who seems to be hugging him tightly and tries to kiss him, and his sister is appalled with this development, "what is this?"
"Sister in law, I really wish you could stop disturbing us since I'm trying to procreate with your brother."
"We are not doing anything! Get out before I burn you in places that really hurt!"
"Awww Sol, how do you even know I love a little pain?" Lune facepalms from the comment which makes Vivian sounded like a real masochist, and the brunette puts a finger on her lips while moaning, "you can tie me up and use me like an object, or even punish me with your fire and sword, since that's my kind of alley."
"Vivian, please go back to the girls' tent before I knock you unconscious."
"Who needs consciousness when I can be on a high while-" before she can finish her sentence, Chilve who is getting bored with the situation dragging on smacks on her neck, where she falls down with a huge thud and faints immediately, and after checking it by kicking a little at her leg, he turns to look at Lune and asks, "why didn't you just knock her out?"
"It won't happen smoothly when her attention is on persuading me, right?"
After carrying the brunette back to the tent, Chilve takes a quick look at Lune and smiles, "good night, my moonlight," her face blushes at the word 'my' and before she can retort, he exits the tent and Lisa smirks, "are you both dating?"
"Huh?! No way~ Hah hah hah…" she quickly lies down and slips into her sleeping bag and turns away from seeing Lisa's face, "good night."
The redhead chuckles softly and after a few shuffling sounds, it quiets down, "tomorrow will be another day of a great adventure."
Meanwhile, Chilve has to camp outside as Sol chased him out, saying about not wanting to share his sleeping space with another person and he starts thinking of ways to annoy him further while poking the fire with a stick.
