I hope anyone can help me find or remember the title of this FF Christmas novellas

The MC is compared to Rachel Maddow and fell in love with her straight co-worker.
I remember she is a researcher for the company and the straight girl is a relative of the boss or something.
She has a guy bestfriend who is married and has kids.

Their story continued with a second or third book? All Christmas themed.

Hoping someone could remember xxx
