The one thing I personally love about him is the way he sees life. I have never seen him in a bad mood [maybe he is when he isn’t on onscreen] but I’ve seen the other members with a bad mood which makes them less approachable compared to Chen. And then the other thing I adore about him is his efforts to learn Chinese [they are quite similar to Kyuhyun] They both actually make an effort to do it not because they have to sing in that language but also for the sake of succeeding in the future and to not create a hassle during interviews.
