A.N/: Thanks so much to everyone! I love all your reviews (and I'll think about the proposal^^)!

Nothing much happens in this chapter but I think it's still funny, so enjoy!

Chapter 4

"Rin! I'm hungry, I want sukiyaki!" Kuro jumped onto his master as Rin lied flat on his back on his unmade bed.

Rin didn't answer. He had an arm over his face and the other on his stomach. He sighed tiredly, rubbing his eyes with his hand.

"Ask Yukio…" He let out.

"But Yukio doesn't cook sukiyaki!" the demon cat complained poking Rin's tummy with his tiny paws to try and get a reaction out of him. He only sighed in response so the Cait Sith got angry and started jumping up and down on his master's stomach chanting 'Sukiyaki! Sukiyaki! Sukiyaki!' like a little kid.

"Stop that Kuro!"Rin raised his voice. Kuro was startled at that but calmed down after a while. Rin remained quiet though, which was very unusual. Rin played with Kuro whenever he could and was cheerful most of the time so he didn't understand what made him so silent.

"Rin, what's wrong?" Kuro inquired, lifting his head up from his spot lying on Rin's belly.

"It's nothing Kuro…"

"You're sure?" The teen sighed again in reply. Kuro gave up and rested his head on his front paws as he wrapped his twin tails around his small warm body.

Honestly, Rin didn't really know what was wrong. Back at the pond he had felt hurt and out of place for some reason but right now he was utterly and incomprehensibly confused.

Shiemi has a boyfriend. And that boyfriend is his friend Renzo Shima. Was that some kind of betrayal? 'No…It's just…' The truth was that it annoyed him immensely to imagine Shiemi with Shima, or anyone else for that matter. Just to think of her in his arms angered him so much! He wanted to growl but he feared he would wake Kuro up. But why in the first place? Why did he feel so angry? Never had he felt that way before… Another thought occurred to him: 'Does Renzo really like her?' He tensed. The guy was known to be a playboy so maybe he didn't really have feelings for Shiemi? But that would hurt her for sure if she loved him. 'Is she really in love with him?' A voice at the back of his mind told him 'Well obviously, since she's dating him.' But this one thought didn't anger him…Actually, it hurt. He felt like something was squashing his heart or like a clawed hand was clenching it as hard as it could until it bled. Rin was amazed at the metaphors he could find to describe it, because it felt just like the truth…

He brought the hand that used to rest on his stomach near Kuro to touch his heart. He felt it beating steadily: 'Thump thump. Thump thump.' No one could tell how bad it hurt even if they tried to listen to it. He clenched his fist and wrinkled his shirt. No matter how hard he tried all his thoughts drifted back to Shiemi and his heart ached more and more, it was becoming hard to bear.

He sat up abruptly and let out a frustrated shout, not minding the poor Kuro who was jerked awake and jumped off the bed.

"RAAAH! I don't understand!"

"Understand what?"

Rin turned to his brother who had just entered the room. Kuro hid behind his legs, fearing another outburst and Yukio simply stood there in his usual attire. He took off his heavy leather exorcist coat and left it on the hangers as he made his way to a nearby chair and sat down opposite Rin. The older twin sighed for the umpteenth time that day.

"It's nothing…"

"If it's about a lesson…"

"Nah, nothin' to do with it." Rin didn't let him finish.

Yukio remained quiet for a while but broke the silence eventually. "About that, you know your grades aren't getting any better, right?" Rin just grumbled in response. "You should really start working a bit or you'll get in trouble."

'Geez, he really chose his moment…' Rin thought "I don't wanna talk about it right now…"

"Then when? When do you want to talk about it?"

"I don't know! Just not now!" Rin struggled to keep his temper but it was a lost battle.

"Look, True Cross Academy is one of the greatest schools in the whole country, if you don't get good enough grades they'll kick you out!" He still got no reaction from his brother so he decided he would put it plainly. "If you don't improve your results soon you'll get kicked out of exorcism class as well! Do you understand!?"

Rin moved ever so slightly. That was the only reaction he thought he would get but just as he was about to go downstairs and give Kuro some croquettes…

"…I'll think about it."

Yukio turned around, amazed that he actually got a reaction out of him. It must mean something though, Rin was never that easy to convince. He still lied on his bed with an arm over his eyes. When he was like that it was usually because he was burnt out, but he couldn't be that tired even though he had given quite a performance against the leapers earlier. Demons are more resistant than that and knowing his brother, he couldn't be drained after such a 'small' fight. 'Something's off…' he thought.

"Is there something wrong Nii-san?"

'And now he asks' Rin thought sighing again.

"Tell me, maybe I can help." Yukio insisted, leaning against the doorframe with his arms crossed.

'As if…I don't even understand it myself…But Yukio's always been the smartest of us two.' Rin thought pulling his arm off his face. He looked to the side and saw Kuro staring at him with his huge green eyes by Yukio's foot. 'He wants to know too… Or maybe he just wants sukiyaki really bad...'

"How long have Shiemi and Shima been dating?" He asked, sounding as bored as he could although he was boiling inside.

"Oh, it's really recent. I think Shiemi accepted just this afternoon." Yukio explained.

'So that was what they were talking about!' Rin sat up on his bed as he thought back to earlier that day when he had spotted them in the corridor. "And they told you but not me!?" he exclaimed, honestly shocked.

"Actually no," Yukio chuckled slightly. "I heard of it when Shima couldn't help boasting about it during my briefing before the mission. I think Shiemi wanted to tell you personally since you're…" He stopped himself short, afraid to hurt his brother's feelings.

"I'm what?" Rin inquired seriously.

Yukio sighed, fatal mistake. "…Her best friend."

Rin remained motionless. For some reason these words didn't make him happy or proud…He couldn't figure out why, but he felt the imaginary claw clench his heart tighter again.

"…Did it bother you…?" Rin asked lowering his head.

"What?"

"When you heard they got together, did it bother you?" Rin asked in a low voice.

"Why would I be bothered?" Yukio didn't get the problem.

'Dude, he's slow…' "Since you've been friends with her for so long, you must be close to her. So does it bother you that she has a boyfriend now?"

Yukio just stared at his brother for a minute, slowly understanding the situation and getting an idea of what Rin's problem might be. "Shiemi's a good friend to me, I'm happy she found someone she thinks can make her happy, but are you?"

Rin didn't say anything so he thought his earlier guess was right. 'Nii-san, you're so predictable' Yukio sighed "You're jealous Rin."

"What!?" The older twin jumped up from his bed in shock. "What the hell Yukio!? Why would I be jealous?"

Yukio smirked but remained silent, staring intently into his brother's identical but confused blue eyes. 'He's going to realize it in 3…2…1…'

"Wait, you don't think…? OH, HELL NO!"

Yukio let out a quiet chuckle as Rin started scratching his head uncomfortably before turning his wary eyes back to his brother.

"You can't be serious…"He sighed in defeat, sitting back down on the bed and clenching his fist on his chest once again. "Since when have I been in love with Shiemi?"
