As most of you probably know, two Produce 101 S1 trainees tried their luck again and joined the third season Produce 48, although not making the final lineup. These were:

• Park Minji - got eliminated after the Group Evaluations in S1. In her return, she managed to join the Position Evaluation but sadly got eliminated again.
• Kim Sihyun - was one of the youngest contestants on the first season, passed the first elimination and was on the Dance Position Evaluation but eliminated. In Produce 48 she proceeded into the concept evaluation and even got the center position in Rumor. But again, she was eliminated.

In addition, in Broduce, some of the trainees actually debuted beforehand the contest and with that boosted his own fame. To mention a few:

• Kim Jonghyun, Hwang Minhyun, Kang Dongho, Choi Minki- 4/5 of the members of NU'EST joined the second season. With Minhyun debuting in Wanna One and the other three's exposure in the show, their fame really blew up in SK and are now very successful.
• Kim Sanggyun - debuted in TOPPDOGG. His rap skills were highly praised and he was able to debut in JBJ. He now redebuted also with ex-JBJ member Takada Kenta as JBJ95
• Ha Sungwoon & Noh Taehyun - are currently part of HOTSHOT. Sungwoon debuted in Wanna One and Taehyun in JBJ.

TL;DR: So in the new season next year, which ex-contestants and maybe members of debuted groups do you wanna see?
