LOONA TV (2016) : 9x8

Choerry tells the camera that her photoshoot is almost finished. HaSeul explains that she and Choerry became trainees at the same time and they lived close together so they would take the bus together to commute and have become close. She recalls that Choerry said to her “HaSeul can we debut?” and HaSeul said “I think we can do it!” so when she found out that Choerry would be the next member of Loona, it was almost like a sibling was debuting. YeoJin interrupts and tells HaSeul that YeoJin is her sibling.
