Say, "Good morning"

Miko tugged on her nightgown as she greeted her sister, who was brushing her teeth.

"Good morning, Rika."

Rika lit up and spat her toothpaste out.

"Onee-chan!"

Miko rolled her eyes; Rika had been watching too much anime lately and she'd taken to saying random words in Japanese. It pleased their parents immensely since neither of the girls had ever cared about being Japanese, but Miko thought it was tacky.

Rika rushed forward and buried her face into Miko's bosom.

"Don't roll your eyes at me, onee-chan~"

Rika's hands slid down her waist, and Miko quickly pulled her off.

"Shouldn't you be heading to the bus stop?"

"Oh shoot! Ok, by onee-chan, see you later!"

Rika rushed out and down the stairs, grabbing her backpack and shoes from in front of the door.

Miko sighed. Rika was in 10th grade at a private art academy, but she still acted like an elementary student. Shouldn't she despise her older sister at this age?
