When does a popular tiktok usually stop getting views?

I made a big mistake... I posted a video about the pink grey shoe debate, where I claimed that the shoe was actually Hatsune Miku. I didn't expect it to blow up that much, I expected like 2k at best but oh well it got 130k and 2.5m views by now. And don't get me wrong, I think that's impressive and all but I'm a small cosplayer who wants feedback and complements on their COSPLAYS, not on that video that most of the "it's grey!!" Or "who even sees pink" people in the comments didn't even watch until the end. I get notifications off it. Every. Damn. Second. I just wanted to know for how long this will go on and when tiktoks usually stop appearing on people's fyp because they're too old.
