Well, although the protagonist did a lot of bad things in the past, I think it was quite pitiful later on, and he did change his ways. The most important thing is that the author wrote it well. It made me think that such a protagonist, although he is a little gangster, is also quite good-looking.
The first part of this book is very good, but after he met Xiao Gong later, he felt like he had changed into a different person, which was very strange. I didn't like the second part. You can read a small part of the first part.
