Why is SHINee's Jonghyun crying in his selca?

On May 26, SHINee's Jonghyun breaks the hearts of their fans with his 'crying selca'.

He wrote, "Last recording ㅜㅜㅜㅗㅗㅜㅜㅜㅡㅜㅡㅜㅜㅡits sad wuuwuuuu ㅜㅜㅜㅜㅜㅗㅗㅗㅗㅗㅜㅜㅠㅠㅜㅜㅜㅜ aww typo in the middle stay there shawols!"

Attached is a close up selca of him looking sad with his teary eyes. He must be feeling the most gloomy because he wasn't able to spend more time with the fans.

Let's cheer him up!
