Could you write something about now everyone thinks Kuboyasu and the reader are in a secret relationship so Kaidou, nendou and saiki spy on them to see if they actually are (which they are but just don’t wanna tell anyone yet)
Hi! This was such a fun idea, I was super excited to write it. I hope I did it justice! Thank you for your request!

In which the reader and Kuboyasu are secretly together, but a certain nosy trio discovers the truth.
—————————————————–
“Have you guys noticed Y/N and Kuboyasu spending a lot of time together recently?” It was surprisingly Nendou who pointed this out, taking note of the fact their purple-haired friend was yet again not joining them for ramen. More often than not, he’d meet up with you after class and it wasn’t uncommon for his friend group to find the two of you walking home together.
Kuboyasu was not one to often make excuses. When it came to you, however, he made plenty. It wasn’t like they were good excuses, often they were half-baked and seemingly thought up at the last minute. His closest friends naturally found this very odd. It was out of character for him and they were determined to find out what was going on.
“Maybe they’re dating,” Kaidou suggested, laughing afterward. “No, Aren would tell us if that were the case… right?”
Saiki rolled his eyes, letting out a sigh. Of course, he knew that simply couldn’t be the case. Sure, some of your thoughts about each other were a bit strange, but he’d know if you guys were dating. Saiki stopped his own thoughts - why does he even care? It’s none of his business anyway. Nevertheless, the idea of you and Kuboyasu dating stuck out in his mind. He wanted to find out now too.
It was a logical conclusion, really. With the way both of you acted, it seemed just like a secret relationship. But your thoughts just did not line up. It was clear you thought highly of each other, but if anything it seemed like you were best friends rather than a couple.
“Let’s trail them,” Saiki said, deciding he was going to get to the bottom of this. It was weird they never saw much of Kuboyasu anymore nowadays.
“Great idea, buddy!” Nendou said.
“Yeah, Saiki, let’s do it!”
Now that the group was in agreement, they planned how they’d go about this. It wouldn’t be hard. Not that Nendou or Kaidou knew, but Saiki would make sure they weren’t caught. It would all go fine as long as none of them did anything rash or stupid. The only worrying part was Kuboyasu seemed to have a sixth sense for when he was being followed, the three of them would have to be cautious of that.
School ended nowhere near soon enough the next day. Kuboyasu ate lunch with Kaidou, Nendou, and Saiki as per usual and you were nowhere in sight. He didn’t mention you once and none of his thoughts struck Saiki as strange.
Though it seemed as soon as the last school bell rang, Kuboyasu was darting to the shoe lockers. Kaidou made eye contact with Saiki and Nendou, all three of them confirming that it was time to put their plan into action.
Luckily enough, they caught a glimpse of you guys leaving the school. They had almost missed you leaving because of course, they had to run into Teruhashi on the way to change their shoes.
They trailed behind you quietly, making sure they weren’t seen by either you or Kuboyasu. Unfortunately, they were too far away to hear any conversation, but they could see you talking to each other. What surprised them all, was once you were far enough away from the school, Kuboyasu reached out to hold your hand, walking with you as close to him as he could comfortably manage.
That was it. All the proof they needed to confirm their suspicions.
“I knew it,” Kaidou muttered under his breath, “They’re totally dating, you know.” He said, this time a little louder so Saiki and Nendou could hear. They all looked at one another and did a small nod in agreement.
It was then, however, that Kuboyasu suddenly turned around to look behind him. “Shun?” He asked as confusion took over his face.
He turned to you, “Sorry, Y/N, I thought I heard Shun’s voice.”
“No worries,” you happily replied back, “Honestly I thought I heard him too.”
Kaidou let out a sigh, having heard what they said, “That was close, at least they didn’t hear us.”
“Idiot.”
Kuboyasu turned around once again, certain that he had in fact heard his best friend's voice.
“Keep your voice down.” But Saiki’s efforts were all in vain, as they were soon spotted anyway. Kuboyasu’s face flushed a light shade of pink upon realizing his friends had seen the two of you together.
Kaidou knew that now was their best chance to find out the truth. Kuboyasu couldn’t dodge the question if you were standing right next to him.
“Aren,” he started, “Are you and Y/N together?”
“Y-yeah,” Kuboyasu replied. His hand came up behind his neck, rubbing it due to his nerves. He immediately turned towards you, seeking comfort in your presence.
Kaidou’s eyes shot open as he let out a gasp. “I was right! Why didn’t you tell us? How long?”
“We just weren’t ready to say, and maybe a month?”
“Just less than a month.” You confirmed, smiling up at your boyfriend. Kaidou smiled once again, happy for the two of you as he pestered you both with seemingly endless questions.
