It’s an old tradition that during a leap year women could propose to men. This was usually depicted as old or ugly women trapping men, but some art focused more on the role reversal and could be quite cute.
I have a soft spot in my heart for the last one because it plays on the idea of “undesirable” people, a tall masculine woman and a shy effeminate man, finding each other but instead of mocking them depicts it as sweet that she could finally ask him because he was too shy and insecure to ask her.
taking off a mask to reveal what lies beneath as a romantic gesture is overdone, and besides i want to see the romantic or even platonic potential of protecting someone's identity beneath the mask, without any expectation of ever being allowed to see what's under it. picking it up and holding it gently to their face when it's knocked off and they're in danger of being exposed, without trying to catch a glimpse of what they "really" look like under there. throwing yourself in front of them to hide them from view while they put themselves back together without taking advantage or looking back to see what you're protecting. learning to read them by body language, tone of voice, and behaviour so well that you never need to see their face to feel like you know and understand them.
