On the March 23 episode, the MCs asked the two girls if they felt competitive with each other during 'Produce 101'.
In response, Kim Se Jung said, "The first person I talked to was So Mi. My face popped up beside her whenever she was on the monitor. I didn't want us to get awkward but I realized during promotions that she and I can get crazy together."
Jeon So Mi added, "She kept touching me when we were promoting together. She goes 'hey' and pokes me. She's an ahjussi style." To this, Kim Se Jung said, "I like touching her because she has a good body."
