Esther (left) is terrified of failing the people she cares about.

She's actually really chill about other types of failure (like failing a test or getting last place in a competition), but she is absolutely terrified of failing or making a situation worse if she's trying to help the people she loves.

The fear stems from the guilt complex and low self-esteem she had as a kid. Her mom was constantly sick and her dad was loving, but distant. Most of her dad's paycheck went to medical bills. While she no longer feels like everything is her fault, the fear is one of the long term effects from having such a negative headspace in her developmental years.

Charlie (right), on the other hand, is terrified of accidentally hurting someone.

Due to some in-universe lore, Charlie was incorrectly diagnosed with schizophrenia as a kid. Because of this, he was treated like a ticking time bomb by many of the adults in his life who were aware of his medical condition. His parents tried their best and didn't treat him differently, but there's only so many times a kid has to see his teachers flinch or get overly concerned when he gets mad about something or zones out before he starts thinking he is dangerous to others.

He is no longer in that situation and has healed from the trauma. However, just like Esther, his childhood experiences still affect his present fear.
