This chapter is king of like a prologue, so that's why it's so short. :D

Some kind of melodic music filled the whole house as he entered. The afternoon sun shone through the windows brightly as Kisa was walking on the long corridor of the huge building, following the music which made his heart race and his face blush. He took slow steps, and when he reached that certain room, he saw a dark brown-haired boy playing on a piano with his eyes shut. His face was so beautiful Kisa couldn't look anywhere else but at him.

He stood there, watching the boy's play, admiring every inch of movement of him.

"I'm glad you came," he then said, not stop the play.

"Of course. Why wouldn't I?" Kisa chuckled as he took a few steps closer.

This time, the boy stopped playing, turning to Kisa with a serious face, and the black-haired boy narrowed his eyes, not having good feelings about that expression of the other.

"Because my words will break you apart."

Kisa closed his eyes, biting his bottom lip. Taking a deep breath, he took a step backwards.

"Bring it on, Yoshida."

Yoshida stood up, walking towards Kisa who turned his gaze down. He stood across from him for a few seconds before speaking.

"It's not gonna work…"

"You mean… the things between us?" Kisa asked though he knew the answer.

"Yeah. I'm sorry, Shouta. I… just realised it lately, but…"

"Your feelings are fading away, huh?" the black-haired boy chuckled, though there wasn't any funny thing going on. Those words just cut right through him like a sword.

"Kind of, yes."

"Then I'll be leaving now. Thanks for everything, Yoshida," he said, then left the room, and now he walked way faster in the corridor, trying to get out as fast as he just could.

He felt his heart broke into billions of pieces. He felt like crying, but he managed to hold it back until he got far away from the house. He then let the tears roll down on his cheek, pitifully trying to wipe them away. He hiccupped as he walked home, not paying attention to those who were watching him on the sidewalk.

Kisa Shouta in his early twenties got his heart broken for countless times just by choosing the wrong person over and over again.

"I'm done, professor."

As Kisa looked up, he met a reached out hand with a filled paper in it. Yukina Kou, his student just finished his test fast again, and as usual, he handed it in with a bright smile. Kisa took it, and put it down on the desk.

"Thank you. You can leave now," he nodded, and Yukina smiled once again before going out of the door and saying goodbye.

Kisa sighed; he didn't know how he was so fast, but it's always him to be the first to hand in the test, and all of his tests are 100%. He hardly made any mistake. The professor shook his hand, and turned back to the textbook he was reading, getting ready for the next class.

As the day came to its end, Kisa was sitting in his office, correcting the tests. He wasn't really surprised; half of the class succeeded under 50%. He scratched his head as he sipped his coffee. It was already dark outside, but it was usual for him to stay in the school at least until 7:30pm. So, when it was that time, he put the tests and books into his briefcase, and turned the lights off, closing his office's door. As he walked on the empty corridor, he heard someone calling out.

"What are you doing here this late?"

He rolled his eyes in annoyance as he turned around, facing professor Yokozawa, his superior.

"I'm on my way going home as you can see," he answered.

"Show some respect, I'm your superior after all."

"I'm sorry, professor Yokozawa," Kisa said, trying his best to hold back his sarcasm. "Anyway, I'll be leaving first. Good night, professor!"

"You didn't answer my question, Kisa," he said, not letting the other go. "Do your work properly so you don't have to stay in."

"I was correcting test," the black-haired man said, his anger rose. "And I always do my work properly! I'm always well-prepared for my classes, and never missed any. So, please don't tell me something I already know! Now I'll be leaving. I still have works to do."

Without a greeting, he left Yokozawa behind, taking fast steps towards the door. There were no words to express his hate towards that man. Anything he said annoyed Kisa.

Outside the building, the cold air blew into his face, and he pulled his scarf up to his mouth. It wasn't too much help, but that was all he could do.

He started to walk home on the sidewalk full of people. He passed the bookstore he often visits, and he saw Yukina coming out of the building. He knew the brunette boy was working here; whenever he visited the bookstore, he saw him. Kisa thought night shifts would affect his school work, but then he figured the boy was able to succeed at both places well. It made him curious about how in the hell he managed to be a good student and work well at the same time. But before he could find an answer, he just dropped the question.

Kisa passed. He had nothing to do with his life, had he? Of course he was his teacher, but his students were already adults, so whatever they do is their decision. He can't tell them what to do after all.

As soon as he got home, he took a quick shower, letting the hot water fill his body. Then he sat down in his living room, correcting the remained tests. It didn't take so long, so he reached the last one soon; Yukina's. With a bitter smile, he made red marks on it, then wrote 100% on the bottom of the paper.

The brunette's smartness reminded him of another brunette he knew; a brunette that broke his heart years ago. If he said he didn't miss the times they spent together he would lie. He loved Yoshida with all his heart, but he left him. Kisa didn't understand it completely, but he accepted it, and move on, though he got sad when memories crossed his mind.

He sighed, as he pushed the tests aside, sitting back on the chair, staring at the ceiling. He really wanted to forget about his ex-boyfriend, but it was hard. Especially when a student of him reminded him. Even Yukina's appearance was completely like Yoshida.

He then stood up, going into his room to get some sleep.

After taking the books he needed, he left his office the next day, going to his first class. Though he tried his best to concentrate perfectly, he couldn't help himself, but thinking about his dream he had last night. It was about Yoshida; their breakup just repeated, and no matter how hard he tried to stop it, he just couldn't. Though this wasn't the first time for him dreaming about this, he woke up in the middle of the night, eyes wet from tears.

This is the reason he was so relieved when the day ended again pretty quickly. In his office, he did the usual things; reading through tons of textbooks, preparing for classes, and when 7:30 came, he got ready to go home. But now, as he was walking in the corridor, he heard a familiar sound. A melodic music. Piano music.

His heart started to beat so fast it was about to explode. He ran, following the sound unconsciously, until he reached the music room. The whole thing was just like back on that certain day.

"Yoshida?!" he opened the door, yelling the name the music reminded him of.

The one playing on the piano stopped, slowly turning to him, a bright smile appearing on his perfectly built face.

"No. I'm Yukina Kou, professor."
