So apparently Dongwoo and Hoya, fought during the Chaser promotions.  But, hearing them explain it.  It sounds like a confession of their relantionship.  Am I just imagining it?  This is what they said.

Hoya:

"We did fight one time. We normally don't fight, but we fought during 'The Chaser', perhaps we were 'chasing' each other too much." 

Dongwoo:

Dongwoo added,"The last time Hoya and I fought was about two-three years ago when we were promoting 'The Chaser'. After having that fight, we haven't fought since and we actually became closer."
