The suddenly silent atmosphere made Shen Qiushan shift his attention from his phone to the two children.
"Xiaoxiao, what did you just say?"
Shen Qiushan looked at his son, who was stretching his neck like a big rooster.
"Dad, I discovered a secret!"
"Our Teacher Chen has a boyfriend!"
Unable to hold back any longer, Shen Yixiao immediately said.
"Uh...?"
Shen Qiushan was stunned, shocked: "How do you know that?"
"By accident!"
Shen Yixiao chuckled, then glanced proudly at Shen Yanran before saying, "I went to the bathroom once during tutoring!"
"I found a pair of men's slippers near Teacher Chen's bathroom door, and they looked like a size 43, so I inferred the person is about my height."
"Also, there are two towels hanging next to the sink in the bathroom, one light-colored and one dark-colored, which means Teacher Chen's boyfriend often visits her home."
"Dad, do you think I'm right?"
