EXO's Kai cried tears of regret during a fan signing event he attended with D.O. on June 22.

The idol opened up, "I don't know if my heart and everything I wanted to tell you were all expressed during this short talk. Later, when the opportunity arises, I want to have a really long conversation with everyone."

Kai also brought up his recent injury which had many EXO-Ls worried. He said, "I will always do my best and not get hurt. I'm sorry. I think you were all really concerned because I was injured so badly. I will not get injured anymore."

As he was finishing up his thoughts, Kai became emotional, unable to hold back the tears which stemmed from his sorry heart toward the fans. Despite his tears, Kai managed to promise fans, "I will really do my best."

D.O., in an attempt to console his bandmate, said, "He may not show it or express himself but he is very tender-hearted."
