"Chuck ! Out of your room, I have to talk to you !"
Thomas waited for a few seconds before sighing and rolling his eyes. He could hear the music flowing out of his brother's earphones from the kitchen. He took a deep breath before his voice echoed through the apartment.
"CHUUUUUCK !"
Rumbling sounds came from the younger boy's bedroom before the door opened and the music stopped. Chuck walked to his brother, scratching the back of his head in a forced nonchalant way.
"Oops, sorry... didn't hear you," he explained with a nervous laugh before adding, "What did you want ? " Thomas pointed at the opened laptop on the table in front of him.
"I just looked at your marks. What happened ? You used to be the first, especially in history and physics." Chuck stared at the screen. E- and F on his two favourite subjects. That hurt. "You remember your first two weeks of high school ?"
Thomas nodded. Oh yes, he remembered it like it was yesterday. Not because he was only 21 but also because it had been, with no doubt, the worst weeks of his life. Having been called the « greenie » for the entire first school year, with only one friend, Minho, the sassiest Asian kid on earth, he had spent his studies looking up to the cool kids of his class.
Chuck kept on talking. "Well when I attended the first history and physics lessons, I almost passed out. No kidding. It's so different from last year, and I'm like, always lost !" The boy shook his head while letting out an exasperated huff.
"My physics teacher also wants to see you to talk about it," He added, before finishing in a lower voice, "I'm sure you'll like him. He's totally your type." Thomas shot him a death glare after his brother winked at him. "Don't try to make me date your teacher so that you have better marks. I'll pick you up at school tomorrow evening, we'll talk for two-three minutes and we'll be done with that."

Chuck let out an amused laugh, earning another stare from his brother. "I'm sure you're impatient to see him."
The two of them ended the day by a dinner - as always, it was mostly pasta - before they watched TV for an hour or so. Thomas ruffled Chuck's hair before his brother went to sleep. He talked to Minho through the phone like the best friends they were, then turned off the TV and walked to his bedroom. He prepared his bag for university the next day and went to bed.
Thomas thought about what this teacher would be like. Chuck knew him enough, after all. He hoped his brother was only talking nonsense, and he turned off the light with that question in his head.

The next day wasn't different from any other day. Thomas and Chuck got up and respectively prepared for university and high school, ate a quick breakfast that they were going to finish during class anyway, then took their bikes to go. It always reminded Thomas that he needed to get his driving license, but if he did, he would be way too short on money. "Maybe when I finish uni and find a job..." he always thought at last. The same every morning.

High school was on the way to the place he had to go to, so as always, he dropped Chuck off, ruffling his already messy and curly hair. He arrived in his own school, an engineer school that was specialized mostly in electricity works.

Thomas was one of the best students, mainly because, as all his teachers said, he was curious and couldn't stop experimenting. When the other students were still trying to get to understand a lesson, he had already applied it and was inventing a new machine. Everyone seemed amused by the fact that his full name was Thomas Sone, so close to one of the best inventors' name. He liked that, in fact. It made him feel like he actually had a purpose in this world.
At the end of the day, as promised, Thomas went to pick Chuck up. The curiosity of seeing what his brother's teacher was like had tingled him since he had woken up this morning. He was so impatient that he didn't bother taking off his glasses, which gave him a /VERY SEXY/ engineer look. His washed-off grey shirt's sleeves were rolled up, uncovering half of his arms, and with his hands in his pockets, he carried his heavy bag on his shoulder.
Thomas asked in which room the teacher was and a group of teenage girls answered him with fangirling giggles. After climbing two pairs of stairs, Thomas found the place, waited a few minutes then knocked on the door, slowly opening it. He spotted Chuck sitting in front of the teacher's desk, next to another chair that was probably for him.
From there, all Thomas could see was the back of a thin man, probably slightly shorter than he was. He was writing things on the board, something linked with Inertia law. He was indeed the physics teacher, and his voice welcomed Thomas in as he kept writing on the board.
"Mr Sone Thomas ? Please sit down." Despite the short sentence, he could easily spot the strong British accent. And before he could sit down, the voice's owner turned around to look at him.
Thomas clumsily let his bag fall on the ground, producing a loud sound. His mouth was slightly opened in surprise and he almost fell on the floor when he tried to sit down.
That guy was a f*cking cutie.
