Got me pregnant and refusing to take responsibility

"Humph, then leave. I can't expect anything much from people like you. Faded suits and old mecha crafts, you must be from the exiled stars, right? Pretending as if you know better than the rest," said the thin woman. 

No sooner did she finish speaking, than the burly woman walked over to where the thin woman was standing, she growled at the woman, "I would be very careful with my words if I were you, missy. Look at your size and then look at mine, one fist of mine is enough to knock you to the ground." 

The woman began to say something but was interrupted by the burly one, "And I am not an exile, even if I live at a star which is far from the Imperial Star. So even if I smack you on the back of your head, you won't be able to do anything to me." 

The thin woman closed her mouth almost instantly.
