Just recently, EXO's Kai and D.O. attended a fan-meeting, and as the event progressed, Kai opened up to his fans about his recent injury.
In a tearful admission, Kai confessed that he felt that he let his fans down with his injury before promising to work harder from now on. As Kai couldn't hold back his tears, D.O. said some words of encouragement for his friend and said that “[Kai] doesn’t really show or express it, but he really has a pure and sensitive heart.”
Here's an English translation of Kai's confession:
“I’m not sure if my feelings or the words I want to say were properly conveyed during our brief conversations. If given the opportunity, one day I want to talk to you guys for a long time.
I’ll always work hard, and won’t be injured. I’m sorry. I think many of you were worried because I’ve been injured so often. I won’t get hurt [from now on]."
Don't worry, Kai! Just keep doing your best and we'll support you no matter what!
