When first time I met Chen really I thought that he is the oldest member. So without searching about he I just call he Chen hyung. And then , when I be an EXO-L for 1 years I don't know that he is "Happy Virus" line. I just know that when I be an EXO-L for 2 years. Then , I started check EXO member birth date. That how I know who is the oldest and whobis the youngest.♡
