EXO's Lay burst into tears as he thanked his members.

On December 10, EXO's comeback showcase 'Sing For You' was aired live through Naver's V App. The showcase was held at Lotte World in Seoul.

"2015 was not a easy year for EXO. I want to tell my members that I'm sorry and that I love them," said Lay. He had to turn around to wipe his tears.

Baekhyun said, "Lay has been having a lot of schedules in China. He always feels so bad to us that he's not there with us a lot of times."

Chanyeol also said, "All the members have been really busy with individual schedules so it's been a while since we were all together like this. It's nice."

EXO released their winter song "Sing For You" on December 10.
