The comic depicts the sexist reality of the unwanted romantic attention that frequently burdens all women. Ultimately, it fails at humor, since it is not a funny situation, but it does say something about society.
A charitable interpretation of the comic would be to say that it is meant as critical satire putting down male Go players, and that we are meant to cringe at the behavior of the men in the second panel, as we remind ourselves how common this is and realize how it is uncomfortable, at best, and far too often, even worse. The caption of the second panel saying “She is also Mary” reaffirms that she is the same, but it is her environment that is different, which reminds us that we should not blame the victim or fault women for their misfortune of simply existing in a sexist society. The first panel provides a baseline for normalcy, where Mary and her co-workers are each occupied with their own tasks, which contrasts with all of the attention being focused on her in the second panel.
However, given the context provided the original poster, perhaps this satirical interpretation was not really the intent. By trying to cast the situation as simply funny, it downplays the problem of these types of experiences, which are far too common and often escalate to much worse.
