On the morning of March 4 KST, actor Ji Soo posted a lengthy, handwritten letter of apology for his past actions. 

He wrote:

"I would like to sincerely apologize to those who were hurt by me. I have absolutely no room for excuses for my actions in the past. They were unforgivable.

As I began acting, I was able to come this far due to the fact that I covered up my past, and as a result received undeserving love and attention from the public.

But deep inside, I always held a sense of guilt in one part of my heart, and an irreversible regret haunted me anxiously. I was always pressed down by my dark past. 

I now beg forgiveness to those who were undoubtedly deeply hurt for a long time, seeing me acting, and I will reflect on the unforgivable actions of my past and repent. 

I feel miserable and guilty for inflicting so much damage on all of my fellow drama cast and crew members, the broadcasting station, and all those affiliated with the production, solely due to my own personal mistakes. I sincerely pray that the drama will not suffer any more damages.

Once again, I beg for forgiveness on my knees to all those who were hurt by me."

Earlier this week, Ji Soo came under scrutiny for allegations of school bullying and sexual assault.
