"Hyung, don't leave!" a 12-year old Kibum was begging his brother to stay.
"Bummie, I can't" a 14-year old Joongwon said. "I'm sorry" he said.
"Hyung, take me with you. Don't leave me with Mom and Dad" Kibum begged.
"Bum-ah, if I take you with me...who will protect Hyuna?" Joongwon said. "You, little brother have to protect her because I can't protect her" his voice cracked at the last part.

"Taeyeon-noona's busy?" Kibum asked. Leeteuk nods.
"Yeah, she's busy with her thesis" Leeteuk said. "How about you? How are you?" he asked.
"I'm living with Kyuhyunnie and Changminnie right now" Kibum said.
"What? Why?" Leeteuk asked.
"My parents fought during my younger brother's death anniversary, turns out Mom found out that Dad has another family" Kibum said.
"You don't look mad" Leeteuk noted. "Is it because you know?" he asked.
"Uh-huh" Kibum said. "I saw them when we
