Tell me how rude he was?? When?? Is this about their date?? If it is then wouldn't you do the same if someone interrupted or more likely flirt with your partner in front of you? And the girl is at fault here cause she just nowhere appear in front of them and then flirt with Kyungju as if wooyoung is invisible.
And lastly, whether you like it or not, that is the attitude of Wooyoung, since he was born with silver spoon expect that his attitude will be a bit a of bratty and sassy (I like that about him) you can just STFU and LEAVE
