I found the answer to my mystery!

So, I was looking through YouTube Studio and found that the reason my Moonlight Waymark video was getting so many views (well, not SO many, but a lot for me) was because people were searching up stuff like 'Moonlight Waymark Roselia', 'Moonlight Waymark anime' etc, etc. My video is like 4th or 5th from the top and I'm like the only one who speaks English.
