Yohangyul 

The 99z. Taekwondo quitter. Castor-Pollux. You name it.
Yohangyul is the dynamic between two remarkable souls born for each other named Kim Yohan of WEi and Lee Hangyul of BAE173. You know the 'best friends after promotion end' best line? It was them guys.

It's them.

I can't get enough for yohangyul
Yohangyul is the source of my life
