Woohyun badly wants to attend the same secondary school as Sunggyu is attending, but he is not as smart as the latter. His grade does not meet the school's qualification for its enrollees.

"Hyunnie try it. It's better to do something than sulk"

"I am not sulking"

"Yes you are"

"No, I'm not!"

"Fine!"

"Fine!"

"Don't ever complain again. I don't wanna hear any of it"

"I hate you Hyung!" the brown puppy (who is now 13 years old) walks out of the living room grumpily. He walks towards his room and slams the door close angrily with a loud bang.

"What was that?" Sunggyu's mother who just got home asks.

"Hyunnie. I don't understand him. I'm getting tired of it"

Later that night, Sunggyu enters his and Woohyun's shared bedroom. The red fox brought him dinner because the brown puppy did not leave the rooms since their argument.

"Hyunnie~ still mad at hyung?" The puppy did not respond to the red fox, he keeps lying in the bed facing the wall making Sunggyu face only his back. "At least eat your dinner, I brought them". Still, no response.

"Hyunnie. I'm sorry if I hurt you in any way. I am so lost right now of why are we even mad at each other. I know how much you wanted to attend the same school as I am and I can feel that you are really frustrated because things don't happen the way w
