"By the way, aren't you tired after the whole day of shopping? What were you doing in the hallway?"

Xiu tied her hair back up into a messy bun as she answered, "I'm very tired. But when I left all the shopping bags in my room. I decided to go to Regan's place but when I came out... I forgot what I was supposed to do since I saw you."

Ying laughed at the way she said she forgot.

"Hold up..." Xiu frowned as she realized something. "How do you know I was out shopping?"

Ying's eyes widened as she realized her mistake. Exactly, how did she know what Xiu was doing unless she was there? Yes, she was but that point was something to keep a secret from Xiu herself.
