we see MW and Anne stare into one anothers eyes because Anne was telling MW that she trusted them to gouge out her eyes for the formula since there needed to be DNA form a creature, and likely living creature (in this case a human) to complete it.
The full backstory is that MW was an escaped experiment that had been injured and found by Anne, as seen during the news report of Santa Teresa at . Although reluctent MW and Anne learn to live together and while Anne falls in love with MW, MW falls in love with singing and dancing
, as its very self congratulatory and quickly devolved into self depreciation, and seeing visions of Anne hits MW's breaking point. The reason? MW is going through deep levels of imposter syndrome combined w/ the guilt of leaving Anne, and it doesnt help that the elixir Anne cooked up to intentionally gives her striking similarities to Anne--------------------------------------------------------------------------------------------
In the Nico Nico Douga version of the mirror scene at , MW reverts back to their monster form showing also that MW cant fully escape from what they are adding that they feel self hatred, combined with the Youtube version the mirror scene is indicative that MW's uses the Teresa persona to justify that Anne wanted this and was ok with being abandoned which obvious doesnt work as ill explain below
the worms at are horsehair worms, which are parasitic worms that infect mantises and "possess" them to drown themselves in bodies of water to complete the parasite's reproductive cycle. very awesome biologically accurate yuri from nilfruits. thank you yuri jesus 👍
Now the real meat of the story and that involves Anne. If you're paying attention up to this point of the MV, outside of the intro, we do not see a present version of Anne. We see hazy, pastel visions of Anne and the one shot we do see of present Anna at has her head turned. Many would assume is that Anne had died, but in reality present Anne is now blind
