This is like insos law but more mature. Insos law touches on mature themes too, but not in a tangential way. Feelings of loss and inferiority, being easily forgotten etc.
This one deals with it's themes more head first, but in a very mature and realistic way. We've all lost loved ones, and sh and bullying is sadly far too common. It's an intrinsic part of her past, and a big reason of why she is today the way she is. But it doesn't eclipse her as a character. It explains a lot of her motives, but it's not her only driving force. It just feels really realistic and I love her so much.
I see so much of myself in her I just want to hug her and tell her everything is going to be alright.
A story is good when the complexity of the plot is moderate. More than waiting to know more about it, if it's starting to get to intense we will start either waiting for more or abandon it cause it's just- ... anyway, simple and generic doesn't kill [with all my good intention oc]
