White Hollyhocks in the Evening

One day, after the rain, I was walking through the backyard of the old palace in Korea and saw a series of white flowers. At first, I didn’t know the name of it, but later I found out that it was ‘hollyhock’.
It was a rainy day, but the rows of white flowers looked so fresh. If it were a warm sunny day, it would have given me a different feeling, but I thought what was it about the hollyhock flowers looked even whiter, clearer and fresher in my eyes on such a cloudy day.
