I'm being serious. Around like 6-7 years ago, when I first found out about Vocaloid, I thought GUMI was a boy because she sounded masculine in the songs that featured her like (Ex: Love Sickness by Honeyworks).
Also, it took me about a year or so to figure out that Vocaloids were not real... 😢
And I was like, huh, why does Hatsune Miku and the other Vocaloids at the time have so many songs? And I found out that they were vocal synthesizers.
