The lie behind the story!

 "Miss, wait!!" Silvia replied quickly, preventing Hazel from leaving. "S-I'm sorry. Please forgive me, I said like that because I've been too curious since hearing you mention that woman's name. And it makes me irrational."

 "Hueh?"  Hazel chuckled irritatedly, but she kept thinking of going.

 "Fine, because I also need help with something, so I forgive you this time."

 "So can I see what's in the envelope?" asked Silvia.

 "You better prepare your heart first before seeing what's in this envelope! Take it easy, it's yours, and I'm not interested in the contents of this envelope."

 "I-I'm ready." Sylvia herself didpn't know what was wrong with her, but ever since Kaili's name was mentioned, her heart was beating strong. She really couldn't control her heart. She was afraid, what she had been expecting was the truth.

 "Yes, whatever." Hazel immediately gave the brown envelope to Silvia.
