Could You Please Help Me with a Girl Behavior Analysis?

I work at a company in Western Europe. One day, a girl from another company came to my office, shook my hand, introduced herself, explained what they do, asked for my name, and we had a conversation. I made a joke, and she laughed. Since that day, because my office is in a corridor she passes by, she has been greeting me every morning by tilting her head and smiling in different ways ( animatedly). She is sociable based on her behavior with others, but I have also observed her being very serious at times. We've had short conversations since our first meeting. I noticed many times that she would glance towards my office, and when I saw her she would quickly look away very seriously without smiling ( before I requested to connect with her on LinkedIn) One day, I kept looking at her when she looked at me she slowly looked down. Despite these interactions, the greetings always continued, initiated by her in her own ways. I requested to connect with her on LinkedIn, and she accepted. The next day, she messaged me at 9 am to get my number for a group chat her company wanted to build for the offices in the corridor. That afternoon, her boss requested my number again! After this, we had more prolonged eye contact. One day, I accidentally called her number and apologized, explaining it was a mistake while checking the group members. She didn’t see my message until a week later, when she sent the first message in the group chat. I replied to her, and she saw my old message. Despite this, our greetings and eye contact continued as usual. we had about three seconds of direct eye contact with a smile, after which I looked down. Later that evening, we had another eye contact moment, where she smiled and looked down. Now, I haven’t seen her for two days, and I’m unsure if she’s on vacation. Could you please analyze this behavior?
