This was very explicit but I didn't quite like it so I tuned it down. Still,
NSFW Content ahead!!!! (might hurt a bit, but it's short)
Right now, (Y/n) was probably watching a movie with Moriji, all cuddled up on his couch, sharing a blanket, some popcorn, and probably some kisses. Or maybe they were sleeping, it was late, after all, but it sounded unlikely. Maybe they were playing some games together, shoulder to shoulder, or worse, (Y/n) in Moriji's lap. Or maybe they were fucking. Maybe (Y/n)'s lips were all over Moriji's body, or the other way around. Gojo didn't know which one he hated to visualize the most. Or maybe they were cooking some late-night snack together, throwing some whipped cream in each other's face while laughing and having fun... No, that was the only thing they couldn't be doing because if there was one thing Gojo knew it was that (Y/n) did not have fun with Moriji like she did with him. If there was one thing he was certain of it was that her smile wasn't nearly as honest and heart-striking with Moriji as it was whenever she was with him. He knew that she simply wasn't as happy with Moriji as she was with him. And yet, she was with Moriji and not him.
It's not that he wanted to be in Moriji's place, not completely at least, not in the compromising place a relationship meant. Whenever Gojo thought of these things, of how much better he was over Moriji, he always did it with the simple thought in mind that she'd be better spending time with him; and that he'd be better spending time with (Y/n). Non-romantic and non-meaningful time, but time nonetheless. And he knew (Y/n) thought the same thing, he knew she felt the same way. And the fact that she refused to acknowledge it bothered him.
The fact that time and time again she chose Moriji over him, over and over again, irked him. But he didn't need her, he could have fun on his own. He had Suguru to spend time with, even if he had lately been more busy and couldn't spend much time with him either... But he had literally everyone else to bother. And he had all the fangirls in the world to entertain himself, so he did not need her, at all. Not even tonight, when she had ditched the whole group to spend time with, of course, Moriji.
It was that time of the month when the whole group went out at night. Yes, some usually left earlier like Nanami and Suguru, but everyone went. Everyone but (Y/n). Hell, she hadn't even had the guts to tell Gojo that she would not go last minute, instead he had to hear from Shoko when they were leaving the school. But he wasn't bothered anymore, he didn't care.
She could be buried deep in Moriji's sheets, and he would not care. He couldn't care, not when he had the plush lips of a (h/c)-haired girl latched in his neck, and the hands of a bold brunette working their way down his body. He hadn't even had to wink or take his sunglasses off when he already had a group of admirers right as he stepped inside the club. He'd say he had picked up two random girls, the prettiest of the group, and left with them to a more private place. But he'd lie.
Maybe the two girls that were on him were the prettiest of that group, but they could not be compared to her. He could not stop comparing them to her. How could he when he had unconsciously —or perhaps very consciously —chosen a girl that resembled her?
It was all due to that stupid video he took of her sleeping on him. He damned himself and the time he decided to record it to 'use it against her' in the future. But he never used it, and instead, he spent his free time looking at it. And every time he looked at her all he could think about was that video and the events that had occurred before he recorded it. He couldn't stop thinking about the way her breath got caught up in her throat when he teased her from that close, when he had her pinned under him, making her give into him and call his name so... desperate. It was nothing like these random girls he didn't even know the name of called him.
But he did not care. He was Gojo Satoru and he could do whatever he wanted to do, like she was doing right now probably in Moriji's bed. So he did not care. Even if every time he closed his eyes and tried to enjoy this all he kept seeing was her face. Even if he found himself wishing it was her body his hands were touching, and her lips his tongue was licking. Even if he had two girls caring for him, if he could have more than one girl at a time... Yet all he wanted was one girl he could not have. But he did not care. And as much as he wanted to moan her name, as much as he closed his eyes and imagined it was her the one doing things to him, he would not do it. Because he didn't care, because she was nothing that special, and he was.
"Gojo-san," one of the girls called him when his phone kept ringing somewhere nearby, making him open his eyes with a frown.
He shouldn't have been bothered by it, he had never been bothered by any of his past hook-ups, not while they were in the middle. But he was now because he had been so caught up in his delusions that this was not the voice he had expected to hear. And thus he was hit with the hard reality that this was not (Y/n).
"Shut up and keep going," he spat with a deeper frown, even more disgusted by his own realization.
But his phone kept ringing, and it was only pissing him more because it was making it more difficult for him to go back to his deceptions. He pushed away from the girls, turned off from his broken fantasies, but it was nothing compared to how he felt when he saw the caller's ID.
"Gojo~" the brunette called him with need in her voice, approaching him. He cringed and pushed her away.
"Not a sound," he warned the girls who patiently and obediently waited for him. Then he turned around, and put some clothes on as he answered the phone with unconscious worry in his voice when he checked the hour: 4 a.m.
"Satoru..." his heart stopped when she heard her voice. A thin voice he had never heard from her and that made his worry worsen.
"(Y/n)? Are you okay?" he asked, putting on more than just his underwear, and doing so especially quickly when he heard a low and muffled sniffle. But there was a short silence in the other line "(Y/n)? Where are you?"
"I-I'm sorry, I shouldn't have called—" she said with a thin voice Gojo had never heard. His heart sped up, and before she continued he interrupted her.
"Tell me where you are," he said with real worry laced behind his commanding words. He left the room and the place without even sparing a side glance at the girls inside or a word.
"I-I don't know, somewhere i-in Itabashi"
