Depth
From the surface, the water didn't look that deep. It wasn't until Tifa saw Cloud's pointy chocobo hair dip beneath the cool river that she herself decided to jump in. In only her bikini top and shorts, she dove in. The water was pleasant on such a hot day. She swam until she caught up to Cloud, who was, unfortunately, at a point where her feet couldn't touch the river's bottom. Swiftly, she swam back to the bank. When she got there, Cloud was already waiting, blond hair messy and wet. He smiled to Tifa, and she wasn't afraid anymore.
