I'm not a fan of watching survival shows since I'm an emotional wreck but my curiosity got the best of me to see some preview of the episodes and OH MY GOD DID I SEE CHANGSUN AND JINHONG FROM 24K AND GUNMIN AND JINYOUNG FROM PRODUCE 101 S2 AND CHANGSUN'S NUMBER WAS 124 (BLESS YOU FOR THAT) AND GUNMIN HAD PUT HIS HAND ON JINHONG'S SHOULDER (WHAT A SMALL WORLD)?!! AND I SAW THERE PERFORMANCE IN FRONT OF THE JUDGE AND JINHONG'S SECOND-CHANCE PERFORMANCE, THAT MADE ME CRINGE AND CRACK AT THE SAME TIME AND GUNMIN IS STILL TUMBLING AND CHANGSUN'S SMILE IS CONTAGIOUS AND HONGSEOB CRYING FOR HIS MAKNAE PARTNER AND 24K ARE PROUD AT LEAST ONE PERSON APPEARING ON THE SHOW OMGGG?!!! TOO MANY EMOTIONS RIGHT NOW!!!!!

I also started to like other contestants as well and here is the full list:
 

Kim Hyojin, Jo Youngho, Lee Chandong, Kim Minseok, Lee Rubin, Kang Mingyuk, Im Youngjun, You Myung Myung, Kim Youngjo, Kim Junhwe, Yoon Youngbin, Jo Hangook, Lee Jaejoon, Oh Heejun, Jung Inseong

There might be more coming up so... :O

Sorry for my random screaming! '(-_-)
