idols with weird/quirky/unusual habit or interests

I'm just really curious!

I can immediately remember Q from The Boyz who has a weird liking on chucky dolls, it's so questionable and I just don't get how he finds it cute lol.

Also, I.N of Stray Kids likes trot music, right? It's not weird but I just find it quite unusual? especially for his age. I think other idols are also a big fan of it, I want to know who else.

For a habit, could be voluntarily/unvoluntarily. If I remember correctly, Jay from Enhypen sleep talks, right? One member from another group also sleep walks but I don't remember who.

Really just anything that's not a common habit or interest that you were completely shocked when you knew about it. Could be something that they like collecting weird things, they're into something that people generally dislike or anything quirky.
