I agree with you, but I was considering posting a comment about how this is how incels view things. But it is just a comic, and PBF is always trying to be edgy (and usually hilariously succeeding, I love PBF don't get me wrong lol)

I'll give my last view on this as it seems everyone disagrees.

I don't think I am reading too much into this since it follows the same pattern as the general incel thinking. Was it necessary for the joke that she's looking hot while the male butterfly is a scraggly shadow? And of course she is immediately fucking someone else, instead of maybe just holding hands with some other dude. And of course its someone who looks "very different" also, while there could be tons of reasons why that mouse won her heart.

It is all the telltale signs of incel agenda, although I am pretty sure its a quite old comic and maybe even predated the rise of that movement. So I am not saying this was made by an incel but just happens to now depict everything that incels stand for, so, didn't age well.
