"Jihoon-ah, I'm going out for groceries. Please take care of Jionnie."

"Yes, umma!"

"U-umma,"

Both mother and son panicked when Jion started to cry. Yoongi laughed and quickly picked her up, patting her back to calm her down. Jihoon looked at his younger sister worriedly, wondering if he could take care of her when his mother was out for a while.

After Jion cried herself to sleep, Yoongi carefully placed her on the couch filled with fluffy pillows.

"Umma, what if Jion.." Jihoon paused for a moment and bit his bottom lip.

"I know you can do it," Yoongi smiled, giving kisses to them before he headed out quietly, not wanting to wake Jion.

Umma! He cried in his head.

Jion shot up awake and blinked her eyes, searching for her mother.

"Umma..?" she muttered out.

Jihoon who was hiding behind the couch screamed internally. Umma! Appa! Save me!

He regretted for not thinking of any plan while baby Jion was sleeping.

"Oppa, oppa!" Jion called, and Jihoon felt like digging his own grave.

He popped out of nowhere which made her jumped, "oppa's here! Hungry, Jion-ah?"

"Umma..where?" she asked, tilting her head to the side tiredly. Jihoon tried to control himself from cooing by her cuteness.

His head automatically went blank. W-what do I answer her?

"U-umma..is here," Jihoon answered randomly, touching his chest where his heart is located.
