Yoon asked Kwon if he was upset because he got sick when they were supposed to do it (that gray panel where Kwon is kneeling while Yoon is having nausea(?))
Kwon said he didn't but being aware of Yoon's condition when taking medicine would have been better.
Yoon said that he didn't know when the effects of the medicine will kick in, so he does not to want to think much about it because he might not be able to do anything.
So yeah that's what the fight is all about I think
