(Solar: 21, Nayoung/Sowon: 17)

Nayoung casually crashes into Yongsun's room when the older is rushing a project report and stubbornly plops herself down on the bed.

"Kim Nayoung, it's freaking two in the morning and you have school tomorrow-"

"And you have a paper to rush but do I look like I care?" Nayoung cuts the elder sister off and candidly says.

Yongsun raises an eyebrow. "What do you want," she says in a half-amused tone.

Before Nayoung can answer the door is opened and the last sister enters. "What's happening here?"

"Let's talk all night! I'm in the mood to talk," Nayoung clasps her hands together in excitement.

"What?" Yongsun and Sojung exclaim at once.

"Just let me talk because I can't control my lips anymore," Nayoung stretches out to reach for Sojung and drags the standing girl to sit beside her.

Sojung chuckles. "Okay," she agrees with a smile.

"You two have school tomorrow," Yongsun furrows her eyebrows.

"Whatever, once I'm in I'm not going to back out," Sojung plainly replies and the twins laugh.

Yongsun sighs and complies, somewhat enthusiastic as well.
