He was a Red flag during the earlier chapters because he is a spoiled youngest son of his family so he is used to do things on his own ways and will not settle if he won't have what he wants, thus having a personality conflict with euihyun who is rejecting his advances causing taejun to push himself to him in a not nice way. But eventually, he will learn from euihyun to be selfless and think about the people around him.
y'all, is it a good read? is the seme or the uke a red flag?
