Dang, this may be short lived. I think they already had their first disagreement, and the dark haired one has left.
I didn't really see what happen, but the darked haired was out alone most of the night, and when she came back they watched a movie together, but the mood seemed rather cold. Suddenly the red haired one went to bed in the guest room, and the dark haired sat in the living room. They sent some text back and forth for a while, before the dark haired one packed some stuff in her purse, put her coat on and left the appartment. This happened by all means very suddenly, because she left right after she had lit some candles that she didn't extinguish before she left.
