The shower curtain was hung around the bathtub on an oval-shaped rail. The bottom was light blue in color and had darker floral pattern. Feng Bujue normally did not use this thing, but based on his exceptionally memory and his observation skills, he noticed something different about it.
"The color and shape of the pattern are different," Feng Bujue mumbled and pulled open the curtain to inspect it. He examined for a long time, but still, he could not work out what it represented. Even though he knew it was different from his memory, regarding its hidden message, Feng Bujue was baffled.
"Could it be the angle of observation is wrong?" Feng Bujue murmured, but his hands had not stopped moving. He turned the curtain around and around, folding it inside different shapes, but it was no use. "Wait… observation angle!"
