Girl 2 has a jacket on, it doesn't make any sense.
It was only 68 degrees at the room and girl 2 sometimes takes her jacket off.
Girl 2 is where the question comes from (the question of jealousy)
Context:
I was picking up a phone and verifying it's conditions, during that I noticed girl 1 was lying on a couch that's nearby. I found it unexpected since no one does that at the workplace so I looked at her with a curious look. Then I noticed that girl 2 was looking at me from a distance and actually saw me looking at girl 1.
Girl 2 was 15 feet away from me and it was in another room but she could see me. She suddenly came all the way and sat right next to a seat that's right next to me. She sat down and said: "It's cold over there and there's a lot of people". In reality there was like 4 people in the other room in total.
Girl 2 has looked at me from a distance, has initiated conversations with me by herself, almost touched my hand (while she was "distracting me" but I noticed).
