Tamaki and Haruhi break up, but Hikaru's the only one heartbroken.
"Are you still angry with me?"
What made him think he was angry at him? Was it the silent treatment all day or the aggressive side eyeing? He wasn't sure. But the way Hikaru was sitting, slouched over on a log by himself, behind the lake house they'd been staying at, hiding his face, he knew he wasn't happy.
He rarely ever wondered what he was thinking. He didn't have to. He was an open book. He always said what he thought. Hikaru's heart didn't just show on his sleeve, he walked with it, carelessly, and talked with it, thoughtlessly. He practically held it in his hands for anyone to take it. It made it very easy to love him, or hate him. To steal his heart or to break it.
Tamaki supposed that he must've done both.
"You don't even know why you're angry,"
"Shut up," Hikaru sneered, fists full of his own hair. "You're a piece of shit that's why."
"Are you really that mad that we broke up? That you'd call me names?" Tamaki asked quietly, watching as the muscles in Hikaru's back flexed. He shouldn't be provoking him but if Kaoru wasn't going to do it, someone had to. "I kind of expected you to make a fool of yourself in front of everyone, sure. But to be honest, I thought you'd be happy."
"Why would I be happy? because I liked Haruhi?" Hikaru snapped, standing to his full height. He had the balls to mock him now? "Am I not supposed to be angry? Should I cackle and twiddle my fingers like an antagonist in what you think is your cute little romantic comedy? Should I be hovering over her shoulder, hoping she'll see me as a rebound to forget about you? The fuck am I to you?"
"You know that's not what I meant." Tamaki scoffed, tightening his coat around himself to shield away from the cold. "Despite popular belief, I don't actually think everything is about me, ass."
"I did not cheat. You're the only one that thinks that."
Hikaru finally turned to face him, his cheeks twitched and the specks of gold reflected in his eyes looked primal as the sun danced off the water and shown on his face. "Spell it out for me then. You were engaged to Haruhi when you fell in love with someone else. Look me in the eye and tell me I'm wrong. I saw you two at the party this weekend. You kissed Ayame."
Tamaki had gone quiet. He was speechless but it's not to be mistaken for guilty silence. He was just so focused on the fire in his eyes he forgot he was defending himself.
"We already called it quits by then," Tamaki said when he noticed Hikaru beginning to walk away, most likely to finish his tantrum someplace else. "You've never been in love with anyone before so you don't know how it feels or know that sometimes people fall out of love too."
Hikaru inhaled sharply as Tamaki continued.
"Haruhi and I don't love each other anymore. I didn't cheat on her. You just keep saying that to justify being angry, because you don't know why you're angry."
"Stop pretending like you understand!" Hikaru shouted. "I hate it when everyone thinks they know how I feel."
"Then just say what you're thinking, so I can understand." Tamaki shouted back, but he was more desperate. He didn't care if Hikaru was angry at him or thought ill of him but he couldn't stand knowing he caused him grief for whatever reason. "What did I do? Is it because you're jealous?"
"I'm angry because you don't love her anymore-" Hikaru said before he stopped himself. "For fucks sake. Are you happy now?"
After another awkward pause, Tamaki gave a frustrated sigh, pulling his hand out to rub into his hair. "Haruhi isn't exactly heartbroken now is she? So you're just going to have to get over it."
"Come again?" Tamaki grumbled.
Hikaru opened his fist and looked down at the marks his nails left in his hand. "I don't care how Haruhi feels about you. She doesn't love you anymore? Good. You suck."
"You suck." Tamaki muttered under him.
"But it's not fair that you get to be over her." His voice strained, struggling to convey both of his most complicated feelings. Being angry, and being sorry for himself. "You've been together for 4 years. You got to spend everyday with her. You got to live with her, sleep next to her- fuck, you were supposed to marry her next year..."
"And yesterday," Hikaru hesitated, "Haruhi told me that I'm... like a brother to her."
"So how can you fall out of love with her and I can't?"
