Elena's pov:

Why would Mr. Leonardo use a wisteria flower as a bookmark? Out of curiosity, I took a closer look at the dried flower. The color of the flower was still quite bright, and it should have been made recently.

Thinking about the wisteria, I suddenly thought of the kiss we had in the study.

It was a very light kiss, and Mr. Leonardo was rare and somewhat gentle.

I couldn't figure it out, so I closed the book and slowly cleaned the whole study.

But I couldn't read the book of choice, my mind kept going back to the events of the past few days, including the letter....
