The April 1 airing of 'Produce 101' turned emotional once again as the remaining trainees read the letters they had written to themselves 100 days ago. 

Jang Geun Suk asked Ahn Ye Seul how she felt about receiving a letter from herself, and she replied, "Firstly, I had forgotten about it. I don't know why I wrote it and I don't know why everything I wrote makes me cringe. I hope that all my friends on 'Produce 101' succeed using the time on the show as a stepping stone."

Jang Geun Suk then moved onto Kang Si Won, and she said, "My letter reads, 'Where are you right now? Whatever happens, I won't have any negative thoughts, and will focus on the now.' Though I'm watching my friends all debut before me. I get an uncanny feeling because we're all debuting." 

Hwang Soon Yeon also read her letter's contents aloud, saying, "It says that I have nothing to be afraid of if I overcome the now," and added, "Everyone, you all worked so hard." 

Kim So Hye, who grew the most during her time on the show, started crying the moment she read her letter. The letter went, "I don't know if I'd be able to achieve my dreams in 100 days but I hope my father is in the audience then." 

Zhuo Jie Qiong also spilled tears reading about how she didn't get the chance to spend time with friends or family because she always ended practice late. 

Tears rolled down Ki Hee Hyun cheeks as she read from her letter, "In a 100 days, I'll have become a singer who put on amazing performances on stage. I'll be laughing as I recall all the happy and sad times." 

Once everyone read their letters, Jang Geun Suk urged the trainees to "keep the letters until they fulfill their dreams of debuting." 

No doubt the girls have come far since they first started on the show; it can only get better from here on out so keep you chins up, girls!
