I can hyper relate to the FL where the need to put additional pressure on one's self to prove themselves (especially with the status difference) and avoid being a burden to others, sensitive to how others perceive the changes going on in your life. It pushed people I cared about away as well. I totally needed those close in my life to open my eyes that it's okay to not be perfect just to be happy. That being said, she is a bit frustrating to deal with in the beginning (which I probably have been in the past too, lol).
That being said, I can appreciate the side couples where they have their own turmoils as well rather than just being side dressing. Especially with the extra chapters in the end to expand on them.
