Jisung wasn't sure what to call Shotaro, Taro or Hyung? It should be a minor thing since they're in separate groups but living in the same building.

"Ah, morning Jisung." Shotaro gave him a meekly wave with messy hair and fuzzy robe on.

"Hi..Taro Hyung?" Jisung asked out of nowhere as he takes a seat in long kitchen table counter.

Shotaro looked puzzled.

Jisung laughs awkwardly. "Um, I'm two years younger than you, unless just Taro is better?"

Shotaro sits down in front of him now seeming to understand. "I forgot you're the youngest here, so many of you, it's a bit hard to remember everyone's name."

Jisung watched as Shotaro pulled out phone with most of the Nct members as his contacts.

"Can I have your number too, since I'm new?" Shotaro asked with a slight smile.

Jisung immediately pulled out his phone. "Yeah, sure."

After exchanging numbers, Shotaro texted him as he spoke out loud."Well, about the name thing I'm fine whatever you're comfortable with."

Jisung looked down at his phone.

-When we get to know each other better I wouldn't mind if you slipped Taro Chan, sounds refreshing.

Jisung replied back. -isn't that only toward girls?

-it also means close friends, I hoped one day in future, we'll be good friends aside from work.

Jisung looked up from his phone, feeling a bit awkward to continue texting when he's right in front of him. "You understand Hangul?"

"Jaemin Senpai is still teaching me, was it correct?" Shotaro asked worriedly.
Jisung nodded, unaware the phone tracker app his eyes caught on earlier isn't meant for Shotaro's own phone. He thought nothing of it.
