My Deer Friend Nokotan's Deer Waifu Breaks the Internet

In some previous articles we have presented the anime adaptation of "My Deer Friend Nokotan (Shikanoko Nokonoko Koshitantan)", an upcoming WIT STUDIO production that will premiere in Summer-2024 (July-September). The most interesting thing about this is how chaotic the series looks, from a strange plot to characters involved in situations that will make more than one raise an eyebrow.
However, what boosted its popularity tremendously was the opening theme song, titled "Shikairo Days" and performed by Megumi Han, Saki Fujita, Rui Tanabe, and Fuuka Izumi, the main voice cast. The chorus of the song says exactly the title of the franchise "Shikanoko Nokonoko Koshitantan", accompanied by a catchy beat that surely won't get out of your head.
In fact, the production knew about it, and it didn't take long for them to share a special video with this snippet repeating for ONE HOUR. The video shows a hypnotic segment that shows protagonist Koshi Torako dancing with a deer in 3DCG animation that is staring at her.
This video has gone viral uncontrollably on social networks, and some have even claimed that it "broke the Internet", precisely because of the large number of times it has been shared. It seems that musical themes, especially those with catchy lyrics and rhythm, are being an excellent tool to make an anime project viral. Or have they already forgotten about the second season of "Mashle: Magic and Muscles" with its "BLING-BANG-BANG-BORN"?
Some editions have even been created to show this same scene but with characters from other franchises:
