Do you remember the first filmed Hunhan moment?

It was all the way back in 2011. Luhan & Sehun's teasers.

But their friendship goes back even farther.

Being shy, Sehun didn't have a lot of friends. Actually, he didn't have any friends. He said it himself, that Luhan was his first real friend.

Luhan is a very outgoing person. He was friends with everyone. He was closest, though, with Xiumin and Sehun. And of course, the other Chinese members. 

Luhan is naturally funny. He made Sehun smile and laugh a lot. In 2013 there was a lot of Xiuhan, which is great of course, but Luhan was spending less and less time with Sehun.

Then Luan left. Thankfully Sehun was closer with the others by then so it wasn't like he had to start all over or anything, but it was certainly hard. You could tell. Remember when a fan brought a Hunhan poster to an EXO concert? and when Sehun noticed it, he teared up slightly and made a small heart with his hands.

That was probably the last Hunhan moment. Of course all the members missed Luhan a lot; but Sehun probably missed him the most since Luhan was his best friend.
