" Class, make sure to submit your homework to Sanghyuk after this class " the teachers, Mrs Kim said and her students just replied a faint 'okay'. The class rep, Sanghyuk stood up and greeted the teacher. 

" Tae, have you done your homework?  " Jimin asked after Mrs Kim walked out of the class. It was the last class. 

" Of course " Taehyung wiggled his eyebrows. He searched for his book in his backpack. He suddenly stopped when he realised something. 

" Why?  " 

" Hyung!! " he gritted his teeth.

" Yah!! What's wrong?  " Jimin asked.

" Haishh!!! I'm done " Taehyung looked at Jimin while pouted. 

" Why?!! " 

" My homework. It must be my brothers who take it "

" Are you sure?  " Jimin asked while peeking into Taehyung's bag.

" I'm sure. They hold grudge to me " Taehyung fake an angry face. And then his face turned to a worried face. " What should I do?  " he shooked Jimin's arm. 

The guy laughed. " What should you do?  Just go to the detention class " 

" Yahh!!  " 

" Ehemm " Sanghyuk came. " Book " he asked for the book. The other student's book already in his hand. Jimin gave him his book. 

" Sanghyuk-ah, I left my homework at home " Taehyung tried to grin. 

Sanghyuk sighed. " Just explained that to Mrs Kim "

" Okay " Taehyung pouted again. Sanghyuk make his way to his table and took his bag. He turned towards Taehyung. " Let's go "

" Eo?  Okay. " Taehyung clumsily tidied up his table and took his bag, following the guy to the teacher lounge after bid a goodbye to Jimin. 

" Mrs Kim, this is the books. Only Taehyung didn't submit the homework " Sanghyuk said while putting the books on Mrs Kim table. 

" Okay, thank you. You can go back home " 

" Welcome. I'll excuse myself then " Sanghyuk smiled and bowed before walking towards the door. 

" Kim Taehyung "Mrs Kim looked at him.

" Yes, Madam " he looked down with his both hand clutched together in front of his body. 

" What's about this time?  "

" Did your brother prank you again?  Hide your book somewhere at home? "

" Y..Yes. I-I think so " Taehyung gritted his teeth. 

The teacher sighed. " Aigoo " the teacher took the books and put it on the other side of the table. " I can't help but to send you to the detention class " 

" Okay " he nodded, accepting the punishment.

" Go and meet Mr Park. He will be the teacher in charge today. You'll be cleaning the school's gym " 

" Okay. Thank you " he bowed and turned to walk away. 

" Don't think about skipping the detention class " 

" Okay " Taehyung bowed again. 

' I'll kill them ' " Arghh!! " he walked out the teacher lounge and went to the gym. He sighed as he put his bag on the bench and took the broom. " Aigoo, is this what I should get on my birthday?  " he sighed.

He did his work silently with his numbed heart while listening to the song from his earphone.

Taehyung opened the door and walked into the house. It was so silent. Maybe his brother still didn't came home.
