On September 22, TO1 member Renta addressed fans with a handwritten letter, announcing his departure from the group. 

In his letter, Renta wrote, "Recently, while deeply considering my personal future, I shared many thoughts with my family, my members, and the company. After much deliberation, it was decided that I would conclude my activities as Renta of TO1 here, and that I would part ways with the company on good terms."

He added on, "I came to Korea with the dream of becoming a K-Pop idol, and through various experiences and opportunities, I was able to debut as a member of TO1 and fulfill my dreams." Here, the idol expressed his sincere gratitude to the members of TO1 for the precious memories made in the past year. 

Lastly, Renta wrote, "I wanted to show TOgether my growth and improvements from here on, and I'm disappointed that I will not be able to. But I will do my best so that I can return one day as a better version of me. I hope that TOgether always be well and eat well. I'll be well too, so don't worry about me. I love you, TOgether, and thank you! See you again someday." 

Renta, who joined TO1 as a new member in June of 2022, will be parting ways with the group after a year and 6 months.
