The girl has 0 conviction. Her life is boring, she knows it, she hates it and she wants it to change, but she doesn't realize her mindset is the problem in the first place. She wants to have friends but doesn't approach people, she wants to be remembered but doesn't remember anyone, and laughably, she think she matters when in the first place, she doesn't even care about her colleagues. It's just someone with a pathetic life, with absolutely 0 conviction. The only thing that is affecting her is her coward and how much of a pushover she is. It's a incredibly realistic manga, and I hope anyone that relates to the main character just find a little bit of conviction. A life motto I once learned throughout my experiences in life is that nothing you do matters, so just be a shithead in the end. I hope the main character changes her mindset and just find a little bit of conviction in what she does and believes in.
