The person in the photo looked exactly the same as Tiana. Austin suspected that there was something wrong with his eyes. He studied it carefully and realised that he was right. It was Tiana. She dressed plainly and looked 18 or 19 years old in the photo.
How did Tiana's photo end up in Steve's book? Austin also noticed two words -- "my love" -- written on the back of the photo when he was about to put it back in the book.
My love? How was Tiana Steve's lover?
How could it be? How could Tiana be Steve's lover? Steve was old enough to be Tiana's father. Suddenly, Austin remembered how Steve pulled Tiana's hand outside of the teahouse. Did Steve fall in love with Tiana? Was that why Steve handed Tiana the project?
This could also explain why Steve wanted to compensate him with the sports event. He was feeling guilty.
While Austin was pondering, Steve had finished his call and turned around to continue to talk to Austin about the sports event.
