Chapter Text
Kai continued hanging out with them after 'date'. Somehow he convinced himself it would never develop past a silly crush even if he got close to them so he just let himself enjoy it.
"Beomie hyung, if you continue clinging on to me, I won't be able to go to work." He laughed at the way omega held on to him even tighter.
"Good. You should stay."
"I'd love to but I have to go or else I won't have any money to pay for groceries."
Beomgyu sat up straighter, still holding his hand. "You don't have to pay for groceries though."
"You already let me live here for free. If I don't pitch in somehow, people are going to think I'm your sugar baby or something."
"Sugar baby? Would you like to be…"
"Hyung no." He laughed, struggling to get himself free. "Don't even joke about it."
Beomgyu's mouth sets in his signature pout and he mutters something under his breath that Kai unfortunately doesn't catch.
"Are you being clingy because you miss Tyunnie? He'll be back in a few hours."
"Please, I know his schedule like the back of my hand, I'm not expecting him anytime soon. I just want to hangout out with you , but your job is taking you away from me." He lets go of Kai finally and flops down dramatically on his bed.
Kai thought of inviting him to join him at work, afterall his boss was really chill and wouldn't mind Beomgyu being there if he was up for it but he decided against it. The other man was obviously tired, he just finished one of his rare afternoon classes and slumped onto Kai's bed immediately he got back, not even eating or changing his clothes into something more comfortable.
"I'm sorry hyung, I really have to go. I promise I'll hang out with you all day tomorrow." He said, getting up before the sight of Beomgyu's pleading eyes weighed him down.
"I'm holding you on to that promise."
"Of course."
"Is it okay if I stay on your bed while you're gone? I promise I won't touch anything!" He assured. "I'm just too tired to go to my room right now."
Kai smiled softly. "Of course you can stay here, I wasn't planning on asking you to leave anyways. You're obviously tired. I'll text Tyunnie to wake you up when he gets home, okay?"
"You're the best, Kai-yah. Thank you." He yawned cutely and settled himself fully on the blankets. Kai knew he would fall asleep soon.
"No problem, hyung. Rest well." He patted his head gently and with great effort, picked up his work outfit and left.

Okay, Beomgyu was acting weird. Not weird in a way that was creepy but weird as in, concerning. Kai was concerned.
This past week, he had gotten more than half of his clothes stolen and they always mysteriously turned up in Beomgyu's room. The other man insisted he would give them back but… he hasn't.
But that's fine really, he has a lot of clothes, courtesy of Yeonjun, he's not that attached to them.
Then it was clinging. It wasn't just to him, it was to Taehyun too. Taehyun always looked resigned, like he expected it and shot an apologetic look Kai's way whenever Beomgyu decided he was to be his human squishy ball.
Even their movie nights became more cramped than usual, with Beomgyu insisting they all squeeze on the same couch with him in the middle of course.
Then it was his annoyed scent whenever Kai came back from class or his job and met him at home. Beomgyu was unfortunate to have mostly morning classes while it was the opposite for Kai so he always met him at home more often than not. The only reason why Kai wasn't over thinking his weird behaviour towards him coming home was that he always calmed down after Kai had taken a shower. Maybe he suddenly got extra sensitive to smells?
Then it was Taehyun making him concerned. He texted more often, calling Kai whenever he was at home and asking to check on Beomgyu instead of just calling him directly. He told him once that he could always call Beomgyu directly instead of going through the trouble of calling him but Taehyun told him Beomgyu was stubborn and wouldn't talk if he asked him.
Which just made Kai worry even more. Was he sick? Why was he acting extra sensitive and touchy?
Kai finally got the answer to his questions when he and Beomgyu went out together to get some groceries.
They split up to buy things faster because Beomgyu was feeling a bit antsy and wanted to go back as soon as they could. Which was another unusual behaviour that he was showing but Kai said nothing. He was at the vegetable section, picking up the exact ingredients Taehyun asked him to buy for their dinner that evening when a guy approached him out of nowhere.
"Hi, I've never seen you here before." He said, smiling at him.
"Oh I'm here every week though."
"Really?" He sounded genuinely surprised. "Wow, I was here for hours last week and I didn't see you. I'm here once in a while."
"Oh uh, I came here late last week."
"Ah that makes sense."
A beat of silence. "Um, can I help you?"
"I'm so bad at this, I'm sorry. I wanted to ask you out actually." The guy chuckled nervously. Kai thought he heard wrong.
"Ask me out? Why?"
"Cus you're cute?" He said in the same unsure tone Kai used.
"Oh." Was all he said simply, face flushed as it sank in that a cute guy was trying, and failing, to flirt with him.
"Well I-"
"Kai-yah." Beomgyu's voice came out of nowhere. Kai looked back to see the shorter man already walking towards him. Andddd there he goes clinging to his arm again.
"We should go, Kai-yah. I already got the rest of our groceries." He said not even looking at Kai, but at the stranger that was standing in front of them.
"Oh I'm sorry, I didn't know you were taken." The guy said simply and walked away. Kai moved to correct him but Beomgyu pulled his arm to remind him that they had to go.
He sighed and went along with him, taking the rest of the groceries.
On the way home, Beomgyu grew even more restless and Kai shot a quick text to Taehyun to let him know he thought something was wrong. Taehyun told him that it would be fine as long as they came straight home.
As soon as they opened the door of their apartment, Taehyun immediately caught the omega that flew into his arms.
"What's wrong with him?" Kai asked, going through all the things he knew that could cause Beomgyu such distress. He ticked them off one by one in his head before he came upon one and froze, realising what exactly the symptoms were.
"He's going into heat."
