Why did the bracelet suddenly fall off?

Actually, you have nothing to worry about It is normal for the bracelet to fall off, because if you wear it for a long time, the button will loosen or your hand will touch something. External force makes the buckle slide into the buckle. It will deform over time, no matter what material it is. Especially when you say you take it in the shower, it's easier to loosen. LZ is a little superstitious. It's okay. Check your bracelet clasp. There is no prediction, astrology or divination that the bracelet will fall. Don't worry.
