"I'm quite shy so
I don't have a lot of friends."
— Park Naeun— some of Nana's close friends
Tomorrow X Together
Nana is probably the closest to TXT compared to others. As Nana was set to prepare for debut as a soloist in 2016-2017, Nana trained alongside the members predebut. Since Nana and they ended up debuting the same year, the boys like to joke that Nana is the unofficial 6th member and little sister of theirs. MOA and AMI live for their interactions. They have a groupchat together.
— Choi Yeonjun
Nana and Yeonjun always used to tie in monthly evaluations. Of course, Yeonjun didn't know who the so called N trainee was. When they met, Yeonjun was so shocked that the trainee that tied with him was a girl. They actually hit it off quite quickly as they bonded over their love of fashion and dance.
