There are two groups in our office. I am the leader of Group A, and the beautiful female colleague I like is the leader of Group B. I am in the stage of pursuing her secretly. She also has a good impression of me, and I feel a little ambiguous.
Today at work, the vice president of human resources came to our office and called her out. I vaguely heard the vice president introducing a new girl to work in Group B. I continued to draw my cyber cross stitch with Excel without raising my head. After a while, I saw my beautiful female colleague come in with a girl and asked her to say hello to everyone. I was stunned as soon as I looked up. I didn't expect that the new colleague who came turned out to be my ex-girlfriend. When my ex-girlfriend came in, she introduced her basic situation calmly and generously, and then glanced around everyone in the office. When her eyes met mine, I felt her pause, but she didn't feel very surprised.
The most embarrassing thing now is that my ex-girlfriend and my romantic partner are in the same department and we both work in the same office. What should I do?
