Produce trainees who debuted with a different company whose trainees also competed in Produce?

[SLY]

Sorry for the confusing title, I think I can give an example for clearer explanation.

Weki Meki's Sei competed on Produce under Louders Entertainment. Fantagio also sent Doyeon, Ellie, and Yoojung to the same show. They then debuted together.

Same goes with DRIPPIN's Hyeop, who was originally an individual trainee. He then debuted with Woollim trainees who joined Produce X 101.

Last is GHOST9's Junseong who was originally from Jellyfish Entertainment but debuted under Maroo who sent Jinwoo, Taesung, and Woojin.

Any other same instances?

Edit: How could I have forgotten Juri...

idk if this counts because they haven't debuted yet, but kim nayoung was under banana culture and lee sian was under stone. things happened that we don't know about and now we only have this picture. i haven't kept up with them, but... hoping for the group to debut together. they're probably my favorite trainees from produce 48.

other than that, fanatics is interesting because it has p48's kim doah (fent ent, their current company) and produce 101's chaelin (who was under midas ent)

Iirc, they're both under Happyface. Sian even made a cameo in D1CE's MV.
