Normally we read the description of each pool, serves us as guide. Also, it's good to understand the whole context of the image and not only one action of certain character in this case Ryuujou, because Ryuujou's attitude fits more in a pair of tags more than the pool if you think how she is acting towards Unryuu moving by jealously, more than be the center of atention for not having larger breasts.
