I'll not go into super depth with describing this character's story. I'll keep it at that Dom is a lady who kinda hates her life. not much to live for or that she wants to live for. Dead-end job, barely any other skills and only cheap joys and thrills.

Until one day she comes into contact with Mistress Uma thanks to another character named Verijn (the lady in the gas mask), who works as a toy maker/repairwoman and hails from a town inhabited by bondage creatures.

Dom's intrigued and after a while, Uma invites her for a session. Dom engages with the practice of bondage, comes to appreciate a new friend group, dons a kind of alter ego for during "play" in the weekends (the prim and proper blue-haired goth look) and things are looking up.

Thing is: Dom wants this to be her permanent life. WHICH ISN'T HEALTHY.

All the inhabitants of that bondage creature town know this too, and seek to help her. Try to make her develop her own skills and capacities, and to build up a proper life outside of the bondage stuff. To not be defined by this single thing alone and waste herself away on mindless self-indulgence.

Encourage her, lead her to grow into a life worth living as a person worth loving.
