I mean if you think about it... from Kangjoon's perspective, Yoonseul seems to be someone who cares about his image. I mean he went as far as approaching him just to look nice in front of someone who had seen his bad side. So in Kangjoon's mind, there's a possibility that Yoonseul was trying to appease his friends by making bets.
But he's not. Yoonseul doesn't cozy up to people, he just prefer to live peacefully and not make a big deal out of everything. Yoonseul couldn't care less about what other people think of him. So in Yoonseul's perspective, it would be offensive for him to be misunderstood like that.
