A romantic gesture
It seems as if this guy had a big decision to make, and he’s had some time to think about it before his girlfriend returned from her trip. When he decided he was willing to fully commit to this relationship and take on the roll of a father, he decided to let Anna know in the most romantic (and public) way.
The first thing Anna saw when she arrived home after her work trip was this good news. We’re not sure how we feel about sharing this intimate moment, as exciting as it is, with the other visitors of the airport, but hopefully, Anna appreciated this gesture for what it was.
