this is a masterpiece. In a way, it is like she truly learned from her mistakes. It might look selfish and comical, but in reality it is very realistic.
A person who learned from their mistakes can still be somewhat arrogant and knows when to be one and when to actually show sincerity even if that is not 100% true. Nothing wrong with gaining an advantage while helping others. That is actually one of the best ways to live. It is a win-win situation. I hope to see more chapters.
