Life Puzzle

Some people say that reality controls our destiny, but the only person who determines our destiny is ourselves. Some people say that all living beings are chess pieces and cannot be free, but they have never thought that freedom is not about having your wishes come true, but about having the right to choose. In fact, we don't want to be something, but we don't want to escape from our own hearts. This book has a multi-line plot and may have multiple protagonists.
