Well, this is the point of this manhwa. If someone has bad personality doesn't mean that he would stay bad forever. I think the author wanted to show that how a dishonest and rude guy is solving all his life's problem one by one and steps forward with the person he loves. And remember his actual personality was rather gentle and shy when he was younger. Problems made him someone he isn't. In latest chapters, he's just going back to his older self.
then shouldn't you have stopped reading this when you first found out that skyler was so sweet to yeonduk when they were still kids or were you just completely oblivious to that part of the story
Am i the only who doesn’t really like how Skylar turned out? I mean I’m super happy that he realizes his mistakes and how much he’s caused Yeonduk so much trauma but his personality did a whole 180 like it’s not even him more. I feel that the author just completely dumped his old personality to progress the story and his relationship with Yeonduk. This is a really bad way to put it but he acts like a little bitch now
