Re:PETIT ~Starting Life in Another World From PETIT~ 10: Just Resisting Desires of the Flesh - S0.E21

Subaru wakes up to find himself immobile and buried up to his neck under the sand and thought it was Ram being mean to him. Emilia cleared up the misunderstanding and explained they were trying to prevent him from getting sunburn. Eventually Subaru requested help from both of them to be freed and while Emilia was digging up the sand he got his reward.
