"That's not impossible," Gu Junzhu said, "When you waved your hand, if you were thinking about something else, the ring could slip off your finger, and you wouldn't even feel it. In your daily life, haven't you ever done something that you clearly did, but have no impression of? Like when your door is locked, but you don't remember and have to go back to check and confirm."
"Th-that's different!" Pan Xinran stammered, "My ring was a gift from my cousin. I cherish it so much, if it fell off, there's no way I wouldn't know."
"Oh," Gu Junzhu said, "If you cherish it so much, then why didn't you notice it fell off right away? Why did you only realize after you'd left the bathroom?"
"..." Pan Xinran was speechless.
"Are you sure you took off your ring and put it on the sink before washing your hands?" Gu Junzhu pressed.
Pan Xinran opened her mouth, unable to speak.
Honestly, she couldn't remember now.
She had a habit of taking off her ring before washing her hands.
