Sasameki Koto 1x13

Sumika goes with her family on a trip to visit graves and an obon festival, promising to call Ushio when she gets there. However, the house they were meant to stay at got damaged in a fire, so they are relocated to a temple on a mountain which, much to Sumika's chagrin, is out of her cell phone's range, meaning she can't contact Ushio. The next day, Sumika is put in charge of looking after some children. Whilst visiting the river, one of the children, Teru, falls off a tree into the river, and Sumika goes to save him, getting her cell phone wet in the process. Meanwhile, Ushio gets concerned that she hasn't heard from Sumika, wondering if she got caught up in an accident or something. Teru apologises to Sumika for causing her trouble and gets grounded. When Sumika's phone starts working again and Ushio calls it, Teru rushes it over to Sumika who is attending a festival and the two finally get to talk to each other.
