In the other side of the room.
Sana was covering her broken nose with a fan, so half of her face wasn't able to be seen when she entered Xiao Tianyao's room with Xiao Wu Xie.
Regardless of the reason why she was summoned was due to she had failed to give them the exact date and location of the transaction, she was very please because Xiao Tianyao was looking for her.
She could think about that damn letter later and figure it out while trying to get closer with Xiao Tianyao. Sana grinned behind her fan merrily by her own delusional thought.
Xiao Tianyao didn't spare a glance at Sana when she paid her respect and talked to Xiao Wu Xie instead. "Prince Xiao Wu Xie, it was you who brought Young Miss Sana to solve the secret letter. So, why something like this happen?"
"Second Cousin Brother, Sana had deciphered the letter correctly." Xiao Wu Xie didn't want Xiao Tianyao to blame Sana, because it would have directed to him also as someone who recommended her.
