All the Colors of Earth (Natasha Romanoff)

Refugee Marzda Cadanar is a prisoner.

Her days are spent laying on the floor of her cell and goading the guards into fighting her. Until one day she decides to escape. When she's out, she meets a man who convinces her to join his secret government agency.

Once there, she has no trouble making enemies. Including her roommate, Agent Romanoff.

Marzda avoids the woman at all cost, until she physically can't, due to a genetic condition that Bonds her to Agent Romanoff.

Now, she can either suffer until she dies, or convince Agent Romanoff to go on a date.
