There isn't anything cuter or more endearing than seeing one of your favorite idols come face to face with one of their admired artists. It is known within the EXO fandom that Chayeol is a massive fan of Dara from 2NE1. During the MNET Asian Music Awards show, Chanyeol was given an opportunity to see her and possibly even greet her.
Through this picture, you will see that he bowed at her in greeting in the most respectful manner and was very serious as he got to meet her. Hopefully he will have more opportunities to meet her in the future since he seems to really be a sincere fan of the idol.
Fans are easily swayed by this show of complete starstruck awe state from Chanyeol's side. They are supportive and immensely happy that Chanyeol is finally able to meet her, even if just for a little while. They also find it cute how he seemed dedicated to showing his admiration and did not pull any fast ones in the process, because it is also well known that Chanyeol can be somewhat of a prankster.
