(This is based on a HC I have for Moon, which is that when he is very tired and/or low on battery he gets very clingy, especially to Sun) (THIS IS NOT A SHIP!)
(This happens after the video "the new Sun and Moon Pizzeria in VrChat")
Saying it has been a stressful day at the pizzeria is an understatement.
First, when he, Sun, Solar and Monty arrived it was already a mess.
Goomer was talking non-stop about inappropriate things, while running away from Roxanne, who was trying to shut him up, or more correctly, trying to beat him till he shut up.
When they saw this they decided that the old gator would be staying in the back for the rest of the day with Solar, who tried to add something to shut his d@mn mouth when necessary, without success unfortunately and this caused Solar be irritated all day.
On the other hand, Freddy infiltrated in the kitchen and was licking the stoves, which caused Monty to trow a tartrum over it and ban Freddy from kitchen. The gator stayed in bad mood for the rest of the work day and occasionally yelled and glared at Freddy whenever he came too close to the kitchen.
Chica helped Monty to keep Freddy away from the kitchen, but when she would get distracted, he would always try to escape and run away, resulting into a strange marathon in which Freddy was going back and forth from the kitchen to the main area, while being chased by Monty with spatula and by Chica with a guitar.
Sun had to deal with all this stress, because they haven't opened yet, so there wasn't much else to do, but this caused the poor bot to be overwhelmed and stressed very quickly; so he was very nervous and twitchy every time someone approached him, which did help at all in his work.
Meanwhile in his office, Moon received a lot of e-mails and takes that he forgot to deal with the days before and on top of that he was frequently interrupted in the middle of his work by the screams of everybody in the main area and the kitchen and he had to go check it out to make sure everything was alright.
During the afternoon, Sun had an anxiety attack for all the stress, so Moon told him to go home and relax for the day.
So that left only Moon and Chica dealing with Freddy, while Roxanne was helping Solar with Goomer; Monty was done with dealing with the bear so he shut the kitchen up and remained in there until he went back home in the evening, around 7 pm.
In all this, Molten and Frost were taking care of some intruders, who for some reasons where trying to break in the Pizzaria multiple times during the day.
After Monty said goodbye and got home, around 8pm, Solar went to Moon in his office and said that he and Jack(who was helping with Goomer too) were going home too and asked Moon for how long he was going to stay here.
The blue bot said that he was going to finish some paperworks and then he would have come home with Molten.
So here he was, tired as f*ck, finally going home with Molten at the 11:50 at night.
He opened the door to be greated with sweet silence, expect for tye quite muttering of voices from the TV.
He immediately launched himself in the couch, greeting with a muffled "hi" whoever was on couch with him.
"Well, hi to you too, Moon" Solar replied from the other side of the sofa.
Moon didn’t say anything else for a while, resting his face on pillow with his eyes closed.
That didn't last long because his stomach groaned and he remembered that he hadn't anything to eat for the last 7 hours.
Solar snorted at that and said "How much time fince the last time you eaten today?" "At least 5 hours I think, I don't know; maybe more now that I think of it".
Moon stopped then added "Do you where Sun is?" "Yeah, he is in the kitchen, I think he left some food for you to eat from dinner" Solar answered.
Dragging himself up, Moon went to the kitchen to find Sun cleaning the dishes, humming to himself.
He walked to sun-themed one and hugged him from being, putting his head on the other shoulder and his arms around his waist; Sun yelped, surprised by this sudden hug, but relaxed knowing who it was.
"Hey Moon, have you eaten anything yet?" Sun asked; Moon shocked his head.
"Ok, well, I left you some cold pasta in fright, if you want you can eat that!" Sun said with a tired, but more relaxed voice from the stressed one early in the day.
Moon hummed in acknowledgement, but he really didn't want to move right now, he was too comfy holding his twin like this.
Sun shifted a bit in Moon arms turning his head to his twin "Moon~ come on, you need to eat before going to bed, I don't want to wake up in the middle of the night finding you half asleep at the fright stealing food again".
Moon still didn't move, so Sun had stop what he was doing to fully look at Moon, grabbing his head with both hands and make the other look at him in the eyes.
"Hey, are you ok? You're not usually this clingy.." Sun said, Moon huffed "mhh.. yeah, just really tired...", pause. "...and I just wanted to hug you, I feel like I don't do that as much as I should..." He said then, lining in and putting his forehead on Sun's as a familiar gesture of affection.
Sun eyes softened "ohh you big baby~", he then reciprocate the hug and Moon hold his twin a bit closer then before.
After a bit, Sun convinced Moon to eat his food and after they both went to couch, while greeting Solar who was still watching the TV: Moon sat on one side of the couch while Sun sat next to him and Moon leaned immediately in his twin warmth, hugging him and bringing the yellow bot on top of him to cuddle better.
So Sun was on top of Moon, trapped in a hug, while the blue bot drifted in sleep mode.
"Does he do this often when he is tired? Because I never saw him acting this clingy" Solar, on the other side of the couch, sudden asked at Sun, amused by the scene. "Well, yes, but he developed this after he was brought back from the death; I'm not entirely sure why, but I don't really mind, because after a cuddle session like this he is usually feeling a lot better!" Sun responded, smiling at his twin.
Solar hummed "Well, It is kinda of cute, and I see why you compare him as a cat now"; Sun giggled at that "Yeah, he basically is a big one" he replied.
They sat in a pleasant silence until also Sun stated drifting into sleep mode, being cuddle by your twin brother does this effect.
Solar noticed this. He turned off the TV and got up to find a blanket for the two; he put it on top of the twins and said goodnight to both of them before going to sleep to his room too.
The next morning both Sun and Moon woke well rested and happy.
