Valex (Alex, Drippin)
These two are the same age, both 04' liners. When pictures surfaced of the two walking to school together rumor immediately began spreading. But Jiyeon were quick to go out and say that they both attended the same international middle school in Korea before, and that they were good friends back then and still are. She said that Alex always have been nice and helped her with her German, and that they often meet up and have fun together, however it's been harder since they're both set to debut soon, so they just walk each other to school now, as their schools are close by each other. There also were that one time where Alex called Jiyeon in the middle of their debut countdown to congratulate her, apparently he didn't know they were doing a live countdown.
Yuyeon (Yuna, Itzy)
Since it was revealed on I-land that Jiyeon nearly debuted in Itzy, the maknae of Itzy took to their social media and shared a picture of the two from their training days, and expressed her support for Jiyeon, and how she watched every episode and only votes on Jiyeon. Jiyeon has since said that she still keeps in contact with Yuna, but lost contact with the other girls with time, but will still meet up with Yuna whenever their schedules had made it possible for them to do so.
ShinYeon (SHINee)
This isn't just between Jiyeon and one person, but Jiyeon and four people. There have been no interaction or whatsoever between her and the four members of SHINee. But during one episode on I-land she had revealed how big a SHINee fan she were and had even sung and danced the chorus of 'View'. Soon after it was evident on all SHINee social medias that the boys had fallen head over heels for her. All four boys would post about them watching the show, only with pictures or scenes with Jiyeon. Minho even went as far as showing himself voting for Jiyeon and looking all excited afterwards before filming himself reacting to Jiyeon being in the final line up. Needless to say, people really want to see Jiyeon interact with them in award shows.
TaeJi (QT, MCND)

This friendship hasn't been seen by fans, but it's heard of... A lot. Especially by the boys of Enhypen,that complains about them. According to both girls they don't see each other often, but when they do... I'm telling you, CHAOS. Since they both grew up in Europe, we all know they get turnt to the same songs. It's often heard of, that at music shows, if they see the other, no matter how far away, the other would tell out a line from one of these songs and the other would tell back the line that comes after. The moment these two are together or near each other, it's just chaos. No questions asked.
