But it's a stretch, it's like how I could also link this to social anxiety but it doesn't mean it's inherently about that

It’s really not a stretch so much as the most logical reading of the comic. But once you tack on previous comics where the author has donned women’s clothes like the recent maid cafe strips… It’s just not that odd to say, “hey I notice this in you that I once noticed in myself” and affirm feelings.
