This is a really good manga! Fate seems like a big theme here. The characters are likeable and memorable. I'm interested in what's going to happen next.
[Spoilers - my interpretation of the story]
The main character has quite an obsession with living as a commoner. She wants to live unoppressed and free to be herself with no restricting expectations because it's the opposite way of living from her previious life. It's her way of trying to cope from a life of being constantly scrutinized and compared. This is why the heroine felt sick after Mel's first visit with the questions game, because he was analyzing her and she felt cornered.
She's not exactly growing right now because she's not actively trying to overcome the trauma just yet. Of course she will be met with adversity that challenges her and through relationships with others, she might find that peace. Character development and building toughness isn't all sunshine and flowers, building those toughness muscles will force her to come out of her bubble. Eventually through all that I think it will be good for her to finally find a way to deal with the pain as no one builds character or find it easier to bear with trauma if they're hiding away in a cave (in the protagonist's case, the cave of being a "commoner").
This is probably why the other characters keep meeting her even if it were for deviating reasons from how they met in the game. Because in a way, their fates are intertwined. Some things are meant to happen, otherwise they do have free will and as long as they push hard enough. And because the other characters are deviating from the game but also say the "flag" lines, there is the tug of war between free will and fate. The characters do things out of free will, but they are still connected.
Like the branches of a tree, the heroine may cut those branches but new branches eventually grow. Because she is still alive. Her being reincarnated and keeping her memories intact is keeping the story going and that very existence is an anomaly. So it's imperative the branches keep growing, as long as the roots are still there.
And since fate is a common theme, other characters must also have the same feeling of wanting to take things into their own hands and not feel helpless.
Well, I think I was going with something but I've kinda burnt myself out thinking at this point so I'll stop here lol. I like this so far though. The heroine is self aware and I like that a lot
