Taro and Emi play in a river wearing only their underwear. Suddenly both Taro and Emi find themselves with their underwear down (for Taro we can clearly see that the cause is due to the current of the river, for Emi we can think the same thing happened, because it is not shown). Taro, realizing his nakedness immediately covers himself with his hands, Emi doesn't (brief full frontal in distance of both), after an embarrassing silence the two say something to each other and after putting their underwear back on, they start playing again.
