Upon hearing this, Han Kexin's face immediately showed some confusion.
She gently bit her lower lip, her gaze a bit panicked as she looked at her sister, then secretly glanced at Wu Wei.
Her guilty expression was almost written all over her face.
Han Keqian felt even more alarmed, her back almost breaking out in cold sweat.
She forced herself to stay calm, her mind racing.
Could Wu Wei have noticed something?
Probably not.
Even though her behavior that day was very different from her sister's, she felt like using the excuse of being on her period should still cover it up.
What Wu Wei just said was probably a joke and an association based on "twins," not his actual thoughts.
"Really? My sister is usually well-behaved; maybe it's just her hormonal fluctuations that she can't control sometimes."
