She didn't see it happen, so it obviously wasn't something life-threatening.
It probably wasn't a big deal, either.
Xiu Yu then said, "Daddy Ying, don't have too high of expectations. They've been following Jiang Ran for so long, they're always jittery."
"Just the other day, I don't know which girls' bathroom they lurked outside of to eavesdrop, and then they came running to us saying something terrible had happened."
"Guess what, Daddy Ying?" Xiu Yu shrugged. "Turns out a girl in the third year wanted to confess her love to Jiang Ran."
Ying Zijin glanced at her little brother: "..."
"Sister Yu, of course, this is a big deal." The little brother said with heartfelt pain, "Because not only did that senior plan to confess to Brother Ran, but she also brought along a few guys from other schools, thinking to have Brother Ran step in as the dashing hero. Naturally, we had to warn him not to fall for it."
