Yukio tried to focus then book the textbook aside,pouting out a bit. "What is that supposed to mean?Do you think I am not smart enough to teach here?" he asked instantly,getting in his defensive mode.

Then he sighed softly,trying to act as calm as possible. "Besides,you have a lot of school work to catch up on,and you may start now." he even smiled a bit as he reminded that to his brother.

Rin chuckled softly as he shook his head. "Nah that's not what I meant. It's just that when I came here I was still thinking of you as my cute but smart little brother. And not the cool exorcist/teacher you got now. Seems like I sometimes miss the old times." He said sighing as he thought how cute Yukio was when they still were kids. Well the other still got his cute moments but nowadays they were rare.

The demon boy started to pout as he was reminded of still having school work to do. "Oh come one did you have to ruin the mood now? You're a meanie sometimes." The older twin said pouting even more but he suddenly started to smirk. Reaching out he grabbed a book from the table and grabbed Yukio's glasses before he put them on himself. "Those glasses are the key to your smartness, right?" Rin said chuckling as he put on a serious face and looked into the book.

Sadly,Yukio felt the opposite.There were days when he truly missed those childhood days when he and his brother had no care in the world and could just mostly play.It's typical,children always have such a naive and simply view on things. But the reason why at the same time he did not miss those times it because he so hated looking back at his old self,so scared,timid.He couldn't ever even protect himself and it was like he always was relying on his 'big' brother'.

A deep sigh escaped Yukio's lips as he kept thinking about those things but his mood quickly changed as his glasses were taken from him.A small blush appeared on his face.He was not used to being without his glasses and wanted them back.

Yukio reached over the desk towards his brother. "Oi,I can't read without them.." he said as he even stood in order to actually reach them.Just then the classroom door opened.The bell was to ring soon so some female students were returning to the classroom a bit early.

And lucky for them they walked in on a cute sight.Their beloved teacher was blushing which was very rare for them to see and he wasn't even wearing his glasses,being teased by his 'big' brother no less. The two girls stood at the door. The one with black hair tied in a bun held her hands to her mouth,holding in a squeal as she mumbled under her breath. "Kawaii-"

"But I want to get smart just like you." Rin said with a pout and in a childish tone as he dodged his brother's tries to retreat his glasses. It was such a wonderful view even though he couldn't see perfectly through those glasses. Still very nice.

Rin's ears perked up as he heard the intruders. Instantly he turned his head towards them and shot the girls a glare. How dare they interrupt his precious time with Yukio. Sighing he took of the glasses and handed them back to his brother. "You really should take care to not let other's see your cute face besides me." The demon boy whispered into the younger one's ear before he hopped of the desk laid down the book and walked towards the door. "See you later little brother~" He cooed even stressing the 'little' just to annoy Yukio a bit.

"You're not even making any sense,glasses have nothing to do with this.." Yukio protested.Surely he knew that Rin was only making such statements to mess with him but at the moment he could not help but to 'play along' with it and respond to them.

The two girls watched how Rin behaved after he saw them and they felt such curiosity when they saw him whisper something to their teacher's ear.It obviously made the other blush even more so it was even more interesting to see.

As soon as the younger Okumura got his glasses back he instantly put them back on. He flushed deeply as Rin said his last comment before leaving.Yukio stood there with a small frown and a blush on his face.He just knew that Rin was doing this on purpose.Then he just sat down and took the book,turning away to read.Not facing anyone.

Since the lesson started and for the rest of the day Yukio felt strange since he could see how those two were eyeing on him.They had forgotten that their teacher that they admired so much was also someone's little brother.Maybe having that bruit big brother of his around him wasn't all that bad if it made Yukio behave so different.

This was a day when Yukio did not have extra classes to teach and usually would walk back home with his brother but this time,Yukio didn't even wait up for the other.But after he returned home first he did begin to make lunch.

Rin sighed as he sat and class and tried to follow the teacher's talk. Though he couldn't really a lot of times would his thoughts drift off to his brother thinking about him and how cute he looks when he blushes. The demon boy even had to chuckle softly.

Soon the lesson ended and he looked around for his brother since they would go home together at around this time. He couldn't find him though so he just walked home alone. It didn't take him long to go back to their dorm. And when he arrived there he yelled "I'm home! Yukio are you here already?" first bringing his things into their room and dumping everything on the floor then smelling something delicious coming from the kitchen so he looked there. "Ah here you are. I was already looking for you." Rin said a pout appearing on his lips.

Yukio didn't reply to the other as he continued to cook.He wasn't as good at cooking as his brother but he never said anything of it and only tried to improve.Luckily,he hasn't messed up on means badly before. After he was finished he served it on the table.

But this time Yukio didn't wait for his sibling and began eating,in fact,it seemed that the younger aquamarine eyed male was trying to ignore his brother.Probably for making him feel abashed earlier in the day in front of his students.He ate and left Rin with the dish washing as he went to take a relaxing bath to calm his nerves. Today he had more free time so why not treat himself by doing something relaxing?

Rin frowned as his brother just kept on ignoring him. "Hey what's wrong?" He asked trying once more but no answer at all. Sighing Rin grabbed something to eat himself and washed the dishes before getting back in their room.

The demon boy didn't really understand Yukio's behavior at all. Was it because he teased him again? Well probably. He sighed once more as he heard running water. Was he taking a bath? Being nosy he opened the bath room door and looked inside. And indeed his brother was attempting to bath. Smirking Rin got an idea. He still waited a bit until his brother was inside the bath tube before he would take action. So he just said there behind the door that was only opened a slight bit.

Yukio left the water to run into the bathtub as he didn't rush to undress and just cover his lower region with a towel tied around his waist. He checked the water temperature and placed some shampoo close to the tub before waiting a bit more and finally taking off his glasses,placing them near the mirror,fallowed by the removal of the towel as he stepped in the bathtub and sat down in it.

The water was pleasantly warm and it just seemed to take away all tension so quickly.Yukio closed his eyes,letting out a soft sigh as he smiled a bit to himself as he laid his back to the edge of the bathtub.Why not enjoy it whole the bathtub gets full of water.And since the water was still running the younger Okumura didn't even hear the washroom's door being slightly opened.

Rin just kept quiet as he watched the scene in front of him. At some kind of point he felt like a bad person for peeping on his brother, his naked brother. Blushing softly the demon boy quickly shook his head to get rid of that thought. As he waited some more his brother finally go inside. And so did he....into the room that is.

Standing in front of the bath tube he smiled softly before quickly taking of his clothes, turning off the water and then getting inside the water as well. "Hehe. Some long time has passed since we did this the last time huh?" Rin said chuckling softly as he looked at Yukio and waited for the reaction he would get from the other.
