"Self centered FL" when its literally a woman who strives for her career after raising her best friend's kids for a good chunk of her adolescence. I know no one says this when its a man in those typical isekai stories that leave for years on end during their adventures.
It's not if you're smart enough to comprehend a strong FL. Girl is retaking her life, has a new man she loves, and has the space to actually focus on herself for once. She's a very level headed and emotionally mature protagonist. She always put others first and now that she's not she's "selfish?" Damn, just admit you're a misogynist and move along.
Your comprehension is twisted AF
Whenever we got a forest ML, we're getting a self-centered FL. Dropping this. It's really hard to find a well-thought story.
