Eh I like that she was honest and doesn't follow the typical "hide everything from everyone" formula. It's one thing if she does things without thinking about it, but she clearly understands the consequences of revealing things and weighs them against her own desires. I mean she literally says the whole reason she never revealed it until that point is because she understood she wasn't strong enough to protect herself and knew it would interfere with All Might's career. Now that she is pretty much as strong as all might, there's hardly a point in hiding it any longer. Seriously, there's not much that can threaten a healthy All Might Jr. Or at least that's what she believed when she made the decision. She wants to be famous, that's not a story flaw, it's a character trait/(arguably a flaw). Someone who always make the perfect decisions in every situation isn't very interesting to read imo. I was skeptical going into this as well but I'm glad I kept going, its pretty good so far.
