Everyone saying why is Red guy saying all that shit to Yuyang but remember Yuyang recognised him so theyve met before...

I don't think anybody is confused about that they just consider his behavior to be out of character and the situation to be kind of forced. As far as I know they met once for a few minutes and then the uncle told him in a few sentences about his relationship with LiHuan but that's all he knows about him.
And now, all of a sudden they coincidentally meet in the middle of the city and redhead is giving him an eye opening scolding after Yuyang had physically attacked him. That's just a weird situation that is hard to believe.
I love how the artist seems to come into her style as the story progresses . Just binged the manhwa again and the first chapters have slightly different art style its great .
