He’s a nice guy… Even though he have this certain bad attitude, what I love about him is that he’s some what innocent and he clearly is a very caring person. He loves his teammates more than anything.

I love your new song, Kontrol, it is nicely arranged and sung. The song suits you well. I believe you did a good work on this one. Am sorry, I only got to know you thru Kontrol, though I’ve watched Infinite many times, I’ve also seen Woohyun on KBS drama HS Love On. Anyways, good luck on all your endeavors. Thank you for singing warm songs for all your fans, although I know you love rock more. You can do more rock ballads soon. Thank you also to the producer of your album, 27. I would love to hear more from you as a SOLO artist. God Bless you more everyday! Be happy my handsome prince!
