read all the series and I'm just super amazed with how the author showed each characters differences in terms of personality and all, as well as their growth as individuals. No one stays the same, no one can endure pain, pressure, sadness and all other extreme emotions forever. At the end of the day whether we like it or not we need to change either for the better or for worst because that's how we learn and be better version of ourselves.
