Hey victoria I was wondering that this is a fun fact : the song was actually by kasane teto called medicine it's a Japanese Vocaloid song made in 2025-2026,it's only seen in project Sekai sonolus or the hatsune miku colorful stage, if you don't know what sonolus is sonolus is a beat tapping game with tiktok songs and memes and also Vocaloid songs and shows replays of your beats and tryouts what you do, sonolus was made in 2024-2025, the hatsune miku colorful stage only has the best Vocaloid songs by teto,miku, neru, Kaito, Rin, and other fanmade Vocaloid characters too, the hatsune miku colorful stage was made in 2024-2023, the thing is that sonolus can be found in tiktok or YouTube,the same thing like the colorful stage one, yes the levels are append, master, expert, hard, normal, easy, but my favorite song in there has to be, machine love hard version, shrimp miku hard version, ultimate beam hard version,and white happy expert, medicine hard version, goodbye delecation hard version,
