Does anyone know why this person pops up on my share list???

Y’all I am confused. When I go to send a video or when I post a video and that share bar pops down, the FIRST person who comes up is someone I am not mutuals with and I have no idea why. This person is like a friend of a friend of a friend irl, but the friends we do share aren’t my TikTok mutuals and I don’t have TikTok connected to my other socials or my phone number, so I don’t think it’s a mutual connection thing…I’ve visited their profile maybe twice before because I have received notifications in my inbox when they’ve viewed MY profile (which is already weird because they didn’t show up in my profile views, I received a literal notification about it…) so it’s not due to MY frequent page visits…I’m just so confused because they come up before any of my usual mutuals who I DM or any other mutual.

Does anyone have a clue what this is about???
